Whoever designed the Training Hall in Order of Ecclesia needs a stern talking-to.
i once felt like this. until i got everything ready, and with a series of practice, i soon hoarded a pile of robe decolletes, super potions, super tonics and alexandrites.
ruby pins, mercury boots (if u have winged boots, the better), hanged man ring (or rings; judgement ring on the other, if this is your first game), armor of your choice (heart cuirass, if you feel like you’re gonna take lotsa hits, knight or minerva mail for better defense). bring along a decent amount of high potions and when heavily damaged, equip emperor ring before drinking up to conserve ‘em.
every room has a looping system that restarts its cycle whenever you leave the room. use that to your advantage. count mentally: after how many fire blasts can you have a safe jumping window? after how many pedestal cycles can you reach the next pedestal? missed a pedestal?— exit the room to restart the looping mechanism. then count again as you platform the room away.
BUT OF COURSE: i didn’t care to enter the training hall during my hard mode lvl 1 game run. was too excited to kill off drac. hehe.
