In the first (non hard difficulty), it says to ensure to put poison on Aerith for her magic damage. Then in hard description, it says that poison spells are not affected by added magic damage so that materia should be on cloud. so, which is it?

>>1 He doesn’t repeat. So, one of the three he isn’t using. Not very useful.

Most of this doesn't actually read like it's from someone who played this battle on hard mode. First off, you can't run away from the chair salvo best is to dodge, then block - if you try and run, you eat like 2000 damage right off the bat - BAD advice. Secondly, where's the documentation of "Gloom & doom" that gets cast if you attack with the wrong element? Thirdly, control Aeris? She will get nailed with Doom & Gloom, control Cloud and use aeris yourself. Shit advice.

>>2 As if the fight aint hard enough.

Same feels from that reaper guy in kingdomhearts 1. hate elemental enemies.

There is another feature to the fight on hard mode. The hell house will summon additional enemies three times during the fight. First right at the beginning after the initial chair salvo he brings in 3 Tonberries (I'm guessing at the plural). They are automatically pressured so if you work quick cloud can kill all 3 before they get a chance to act. Same thing during second phase once more and finally a sweeper and cutter during the final phase. I suggest saving your summon for the last two.

Does this guy have specific pattern on which element it transforma to or is it completely random?
