Main Weapon Selection

The main weapon upgrade will impact how far the progress you can go with minimum effort to conquer higher wave.

指 (Mouse Click/Hold)

• Most basic weapon
• Less Cost
• Medium Damage
• Good Weapon for Early Wave once unlocked Constant click upgrade
• Works well with legendary item Midas Glove (Obtain from 1st Mega Boss) with more 25% Gold from monsters which been clicked
• Suggestion: Upgrade few levels till constant click skill unlocked, keep upgrading to level 90-100

矢印

• The great weapon for early wave
• Medium Cost
• High Damage to single target
• Good Weapon for Early Wave / Mega Bosses
• Works well for early wave with several items buff for arrow damage/critical damage
• 重大なダメージ ✅
• Suggestion: Mainly focus the upgrade of increase archer amount and arrow fire rate. It is suggested spend remaining money for the arrow damage when player level under 300 (due to the Mastery Skill, ultimate will required to use mushroom to wipe the point spent).

レーザ

• The best ultimate weapon
• High Cost
• Late game best weapon for wave clear
• Laser Mastery: Transform Archers to become Laser Archers & Activate Laser Bounce
• 重大なダメージ ❎
• Suggestion: The laser bounce is necessary to be upgraded once decided not to use arrows. The laser is the ultimate wave clear weapon because starting from Forest Map, there are the healers which arrows unable to handle and difficult for wave clear. しかし, the items and mastery upgrades are high cost hence it is suggested to have at least 1B Gold before deciding transform arrows to laser for the wave clear.

ミサイル

• Not useful weapon
• High Cost
• 重大なダメージ ❎
• Suggestion: No suggest to spend gold on the missile upgrade, unless you want the secret achievement Barrage From Above, but it only required one time for this.

砲弾

• The great weapon for early wave
• High Cost
• 重大なダメージ ❎
• Suggestion: Can spend few gold for cannonballs when early wave clear, but it is still not suggest to spend gold on this due to the unnecessary upgrade will drag the wave clear progress

宝石 / Power Gems Spending

The gems & power gems are rare items but it’s obtainable from game progress or spend real money for better game experience.

宝石 (青) are obtainable from

• Drop from monster killed with low rate
• Perform Local Save per day (10 宝石)

• Drop from mega bosses (Guarantee 1-3 宝石 )
• 12 Hours Treasure Rewards (1-10 宝石)
• Per Level up (1 Gem)

Best Place To spend Gems (青) の上

1. Unlock Research Task Slots up to 3
   
2. Buy Inventory Slot, it is suggested to have at least 5 empty inventory slots for the item dropped especially when doing wave clear
3. Buy Accesory Slot, it is expensive but worth to buy it as it is significantly increase the game progress with more items equipped (gold/exp/damage buff)
4. Unlock Auto-Merge items skill at least 1 if you are afk player (depends on how often you check inventory for new item dropped and item merged)
5. Exchange Gems to Power Gems
   
6. Increase Offline Rewards
7. Skip the rounds/researches by spending gems [Strongly not recommend due to the waste unless you have massive gems]

Power Gems (赤) are obtainable from

• それぞれ 25 wave clear (1 Gem)
• The map with wave clear approximately 500 but to be confirm the factor of different maps (10+ Power Gems)
• Achievement Rewards
• Exchange Gems (青) to Power Gems (赤) and it’s last through Rebirth: 100 Gems => 1 Power Gem

Best Place To spend Power Gems (赤) の上

1. Increase the damage per weapon upgrade
   
2. Unlock the Rocket Launcher for the Bomb Tower, not recommend unless it is for the one time achievement

Rebirth Mechanism

Rebirth is a process of “soft reset” your game progress but you could able to utilize the Rebirth Tokens that earned from Wave Clear & Mega Bosses.

Performing Rebirth will reset

• Game Progress (All Maps), starting from Island wave 1
• Experience & Gold Upgrade
• 才能
• マスタリー(ies)
• Power Gems Usage, reset the power gems obtained from wave clear but exchanged via Gems

If rebirth will reset your game progress, why still doing it? Because you will able to access Rebirth Shop which bring you the massive buff through spending Rebirth Tokens. Here you go the Rebirth Shop Upgrade and you will know it why it’s suggested to perform rebirth instead of stuck at certain progress.

Rebirth Shop Upgrade

• Increase Gold Earned, 5% per upgrade
• Increase Experience Earned, 5% per upgrade
• Increase Overall Damage, 5% per upgrade
• Reduce Monster per wave, -1 per upgrade
• Multiply Amount of Rebirth Tokens gained per Zone, +10% per upgrade
• Multiply Amount of Rebirth Tokens gained from Megabosses, +10% per upgrade

ご覧のように, whenever you feel the game progress is starting difficult, you can start thinking to perform Rebirth as it will give you the buff for next run. Hence the time required will gradually reduced if you have constantly utilize the Rebirth Tokens for the upgrade.

My priority for the Rebirth Tokens utilization:

ゲーム序盤
Rebirth Tokens Multiplier > Experience > 金 > ダメージ > Reduce Monster per wave

レイトゲーム
Experience > 金 > ダメージ > Rebirth Tokens Multiplier > Reduce Monster per wave

Rebirth Tokens Multiplier can be consider as the tokens earned is double/triple when it’s 100%/200%.

Ultimate Guide

The below is my strategy for pushing game progress with minimum effort.

For early wave/after rebirth, I will mainly focus on finger click upgrade and further constant click upgrade (hold mouse) because of significant damage dealt. The plus point is Midas Glove because of the majority damage dealt is from finger clicks which means the gold rewards + another 25% from monsters. I will spend gold till the finger click upgrade till 90-100 level and starting save gold for the next weapon.

PS: You will need to spend the talent points & power gems buff for your primary weapon upgrade even it’s a small cost of the mushrooms that will be required if you want to reset the points spent. But believe me, you will have more than enough mushrooms if you are following my guide.

Once you starting felt tired (if you don’t have auto clicker), you can starting transform to select arrows as your main weapon for upgrade and wave clear. Please be reminded the talent point and power gem upgrade is also needed to be reset. The arrows upgrade such as arrow archers number is up to 7, so it is advisable to upgrade as soon as possible. The next thing need to be concerned is fire rate, it could be expensive because of the gold required is significantly upgrade compared to damage upgrade. But it have a limit upgrade so no need to worry which you are thinking you are spending too much gold on arrows upgrade instead of preparation for the laser weapon upgrade transformation. この時点で, you should be able to conquer first 3 mega bosses because of arrow weapon have massive DPS to single target. That’s an only exception which you have too low health to withstand the damage from mega bosses, hence you may need to equip the items that can increase your health.

At this moment you will thinking it is difficult for wave clear, so it is the best time to rebirth. Rebirth reset the wave progress and every upgrade but it does lasts some important things such as items dropped, gems and most importantly is you can utilize your rebirth tokens which obtained from waves/ mega bosses. The priority of the rebirth tokens spend will be Experience > 金 > Multiplier of Rebirth Tokens obtained from Zone/Mega Bosses. But to be honest, I will suggested to spend the Rebirth Token on Multiplier of Rebirth Token at least 100%, because indeed it’s an investment if you are constantly performing Rebirth in game.

And you managed to utilize the Rebirth Tokens for Experience/Gold/Damage Buff, but be reminded each Rebirth you start from wave 1 with player level 1, which meant you can continue earn your gems (青) from each time level up. I have also stated the best place to spend gems so you know what to do :D.

After you experienced several times of rebirth, I believe you have some legendary items and some items with max levels. しかし, the most important items will be the legendary items that dropped from 3rd mega bosses – Rubber Eye. The Rubber Eye increased the laser weapon damage and also the laser bounce damage. Hence this is the key point you can starting move your battlefield to Forest Map. Why the laser bounce damage is important because of the healers at the new zone is troublesome, if you lack of AOE damage, you might required spend massive unnecessary gold for the damage upgrade.

Here is the another trick which might be useful when you can’t beat the bosses / mega bosses.

You can equipped the items that increase the Health Point before start the wave/raid.

その間, you can gradually un-equip the items that boosted health points and equip the items that boosted damage/critical.

Items that boosted Health Points

• Bronze Ring, 健康 + 20%, +0.2% レベルごと
• ライトニングシールド, Lightning Resist + 10% & HP + 10000, +0.15% と +150 レベルごと
• ファイアシールド, Fire Resist + 10% & HP + 10000, +0.15% と +150 レベルごと
• Dual Shield, Fire/Light Resist +10% / HP + 10000, +0.1% と +150 レベルごと
• Blocking Shield, ブロックチャンス +5% / HP + 20000, +0.05% と +600 レベルごと
