Hi guys, I just wanged to report that i found a two-handed sword that did not come out on the wiki. I put pictures of her location, i think you need a high perception to open the secret passage, at the time i discovered the button I was 21. I have no idea if this weapon was introduced now or always been in the game, but I've played the game several times and it´s the first time I've met her.
It's in the Ori o Koiki Sanctuary
It has a 10% critical damage bonus, and 33% chance to hit in area whith critical hits.
It has two improvements with two options
First: The damage in area sick the enemies or reduce enemies deflection
Second: up the critical damage bonus, 2% for death (20% max) or up the critical damage bonus, 5% for death ally (20% max)
P.S: Sorry for my bad English
