First Play 

When you are on the first play, basically you must know the heroes you get. It is include passive and trigger ability. So, basically that how it is, the basic strategy is just attack and heal. The other activities that doesn’t important like protect, buff, debuff is another aspect when you play this game. For the first play, before you reach the 1000th floor you must prioritize attack, heal, and protect. The side job I use are for protect and heal, for attacking I use mainly on ability card. First, I use intelligence strategy that focused on healing and protect but it lack in attacking, so I switched in full attacking strategy using agility, but it also easily got defeated when meet enemy with full of protection. In the final I switched to Max HP strategy that got balance in protect, heal, or even attack, yeah even though we can side the thinking of buff and debuff

Intelligence Strategy 

First time I am using this strategy, I use pope as starter and main job. The I gained Book of Light, Book of Dark, Book of Thunder, Book of Wind, Book of Earth, Book of Fire, and Book of Water. I managed to reach 345th floor with this strategy. The second strategy is using barrier master job as main and starter and combine it with the tower job. On the way, I acquire some attack ability like ambush, barrier force, force and attack and so on. Just keep attack ability has 0ap, and keep the high star ability like unity strike as the only ability that have high ap in the deck. Somehow I managed to reach 100th floor and got defeated by lonely queen haha..

Agility Strategy 

I just equip job that have 0ap as the ability like devil hunter that has ebony and ivory or witcher that has fast attack ability. Remove all card in the deck except those card and yeah. you will reach 100th floor got defeated by lonely queen that has counter for multi hit attacks haha. For main job I use infinity bleed or sagittarius that deal damage after action. The side job I use protect like guardian pr pirate job. For healing, on the first I use hunter, after that maybe doctor if have higher int stage.

Max HP or Tower Strategy 

I like this strategy that much while the game focused on protect, basically it also give you the chance to attack even though it is less. For main job I use the tower, also I use this as starter. This job is getting well done, even though the confuse debuff make me disappointed when pair it with barrier master that focusing on intelligence stat. So, I use max hp strategy then. It is very useful when you want to reach higher floor. For the side job as healing part I use hunter or pope when it has higher intelligence state. Side job for protect, I use high paladin, or basically I leave this place for damage and debuff job ability.

The hero I am used there is no doubt, it will get easier you get in gacha after reach 100th floor, yeah I use the lonely queen cause it is the best. It has protect master as passive abolity make this best when got paired with the tower bable from the tower job.

For the deck keep attack ability as minimum as possible, I just use ^0[]x, force and attack, move and take, and keep the main attack with 2ap unity strike as the only ability in the deck. Try to keep all attack ability has 0ap or you will be dissapointed cause chill debuff that apply to you all the time. As for healing ability, I use six card that is restart, elemental enchant, high potion, elixir, caffeine, and remedy. To make easier draw card, I use for ability that is exchange, painful draw, supplement, and nap, and to make things complete, I use debuff ability that has 0ap named fancy talk, or maybe cast seed. It will make pretty useful though. Hope I can reach 500th floor with this build
