>>43138116Choco Horns are mroe or less mandatory, Ina's got no sustain without them but they're especially decent on her because her tako ring instakills. Knight Milk for size and Energy Drink for haste means more AO-chan procs, more friendly takos, more healing, more knockback, more everything. Gorilla arms is good for her since she has no on-crit bonuses, but it's flexible.
On the tentacles I put the debuff stamps, sometimes the lifesteal stamp (works decent on her since her tentacle hits slow so she isn't missing out on much from other stamps).
For Collabs, we want area + CC, so I go with Broken Dreams and Frozen Wine. Micomet/Flat Board and/or something else like DragonFire if you want something to focus fire.
The rest is more or less free, Plushie helps a lot but I managed to sit still and tank Stage 1 Hard without it (only choco horns to heal) up to minute 29, because I was doing decent damage.
