This is just a quick runthrough, im sure i missed some key points but for specifics readBuktooth’s Iori FAQ General things to know:
Learn how to RC his rekkas this is a MUST. it has long range and is an easy combo/knockdown.
His sweep has decptive range, but recovery sucks and can leave u open…ONLY use this when u know it will connect AND it is at the very max distance in case its blocked.
If u ever have a reason to jump in, mp usually gets priority in the air, but Ioris game is good on the ground as it is so try to keep it there.
Iori’s man anti-air is cr.hp; hits at a 45 degree angle and is very fast, making it hard to parry or JD…however not too useful vs. blanka/bison probably others. fierce DP has the best priority so always be ready to use it and look/wait for jumpins.
Whenever u are up close always use st.lp to start your combos. This is one of the fastest jabs in the game and usually comes out before the opponents does.
BnBs
lp, lp, cr.lk x rekkas
lp, hp x rekkas
lp, cr. lk, Fierce DP
Focus on these mostly, combo into rekkas for damage, and use the DP combo if u sense the opponent will become dizzy.
when u get a lvl 2 use it when u get the chance, preferably lp, lp, st. lk xx super, and cancel the very last hit into a DP. Level 1s are a waste, so are lvl 3s…dont bother with the pillar super unless u wanna be flashy but we all bizness for now.
Also dont abuse his roll too much, its best to use when the opponents waking up so they have to guess what side youll be on.
