The hitter will need to stack traps, then aura, Shrike, and hit. Do not use blades, this includes global rings such as Darkwind that act as a blade. Any school can hit, but over-time attacks such as Dragon are not recommended. Failing to kill on the first strike with an over-time attack, will trigger an overtime cheat from the Life School Tentacles.
A Storm attacker will want to stack different forms of the Windstorm spell. Use regular and Potent Windstorm along with any other Storm traps you can get your hands on. Four stacked Windstorms is a thing of beauty against this rampant vine. You can achieve this, by stacking Treasure Card, regular, Potent, and pet or jewel forms of the card.
If you are a Storm, and your damage is lower than you would like, keep a Supercharge in your side deck. Any blade will trigger an all one enemy cheat from the tentacle diagonally across from you. As long as that tentacle isn’t Myth this is the one blade you want to risk. With a full pip Supercharge and stacked Windstorms, you should be able to one-shot this boss. Your Treasure Card deck will hold zero-pip shields which you should use defensively while building up the Supercharge.
If you are the hitter, do not run in with the team for the first round of battle. Once the spammer lands a hit, it is safe to join the battle.
