It's about time to add Coil story mode, isn't it ?

Yeah, I haven't noticed a whole row of insta-kill "mechanics" in Ifrit HM, but nvm. In any case, nowhere did I say it's needed; point is it's not as easy when all the other 7 are unknown variables. I've had a fair share of wipes even in T1 and T2 (many times the echo doesn't even come into play because people ragequit after the first and the party disbands).

Don't meet potato DPS check for nails: OH-KO
Stand in middle of arena during charges: OH-KO

And if t5 is an unknown variable, get 7 other potatos like you, watch guide and discuss how2kill twintania (potato edition), run in there and don't forget to focus target.

Here's the kicker, so listen closely: "If the potato is too baked, get new potato."

Congrats, you did it.
