Swaystroll – Water Tank

In-game bio: “Swaystroll once dreamed of becoming a singer, but that didn't work out. Now it's non-stop drumming practice during breaks. You'll be met with an indignant glare if you file a noise complaint.”

How to use Swaystroll

Deploy Swaystroll in the front row, where it absorbs the first Zobos of each wave. As a Water Tatari it should face Fire Zobos and avoid lanes with Lightning Zobos — the game shows a green thumb when the match-up is right. Its skill hits an area, so it likes lanes where Zobos bunch up. Its support effect only reaches nearby allies, so place the Tatari you want buffed right next to it. Swaystroll is T2 — the line gets its full kit at Glideflip, so treat this form as a stepping stone.

Tier verdict for the Waddledo line (A): Water tank with an Ice Shield that fires crystals when it breaks; wiki advice is simply "best deployed in the frontline". Anchors Water Dojo teams from stage 1-10 onward.

Waddledo line Horde Invasion skills

In Zobo Horde Invasion every Tatari learns three extra skills at Horde levels 3, 5 and 7; they are shared by the whole Waddledo line (only the base skill differs per form).

Base	Icepad Bash: Grants an Ice Shield and fires ice crystals when the shield disappears, dealing AoE damage.
Level 3	Ice Strike: Attacks have a chance to fire 6 extra ice shards.
Level 5	Shield Gift: When obtaining a Shield, there is a chance to grant nearby allies a weaker version of Ice Shield.
Level 7	Ice Show: Summons a row of attackable ice sculptures that explode to deal AoE damage when they disappear.

Horde verdict (B): Level 5 shares weaker Ice Shields with neighbours, level 7 summons a row of exploding ice sculptures; solid wall.
