@Kishido:
Can someone give me tips how to get through Garp Challenge 6.
I want the 30 gems before it will be renewed.
What units are just haves? And what is the strategy?
You need quite specific characters: Shira/Mansherry, Kata V2 (with Legend Cracker support LV. 5), Whitebeard/Marco, Vivi/Rebecca, Luffy/Law (with support Bepo LV. 5), KungFuLuffy, Snakeman, Sabo/Koala, Shanks/Beckman, Kaidou.
You don't need all of them but some of them you must have and can build a team with. Shira/Mansherry OR Whitebeard/Marco and v2 Katakuri with Cracker MAX support are a MUST. Moby Dick ship is a MUST. You also need MAX poison resistance.
That said, it's a crazy thing. Some teams rely on a glitch in the game, some rely on Recovery RNG. Almost all need always PERFECT hits through the stages 3-10 while sometimes manually focusing the target. It's crazy. It already took me more than 15 hours only to reach the boss stage using three different teams… and i failed because i became nervous.
I'm trying this team at the moment:
FC Sobamask / Luffy-Law (support Bepo)
V2 Katakuri (support Cracker) / Vivi-Rebecca
Shira-Mansherry / Shanks-Beckman
