I think, i wanted mean the Crystal Vial (blue right?), so yeah, you can't take it at the beginning because you are level 1 so you dont have the max HP.
About the level up, what do we win exactly, hp but also, more defense or?... I have finished 1 episode, i didnt notice the things...
EDIT: Oh...the red rain" of the tomed Hell Staff is not there anymore....Is it possible to add the "spikes ball" of the tomed Dragon Claw or the "red rain of the tomed Hell staff in a way ?
It was the mark of Heretic, the tomed version of those weapons are cool but seem a bit more generic, the tomed hell staff in brutal mod is just a spread, right ?
In Heretic, its an epic red rain.... same for the tomed dragon claw, Knight Spikes balls (kind of)
Do you want add them in the future

(like, with the alt or level up?)
I like a lot this project, but i think, the tome of power and original" strong weapons (specially the red rain) is the mark of Heretic and make it not generic

EDIT2: I was able to test all the weapon (im at e2m2), and omg, the Firemace is really badass, it's exactly what i wanted if there was a remake of Heretic or something, it's now like a true Mini-Grenade Launcher and it's so violent! Also, with the Tome Of Power, you did it perfectly!!! It becomes a Mini Fragmentation-Grenade Launcher and the way you made it is really epic and original! The Phoenix Rod is pretty cool too, in fact, i wasnt sure about that but you have modified the ammo bar type, and it's a good idea so i suppose you have did the same for the dragon claw, i noticed i still had enough ammo to shot, but i wasnt sure about the system.
So yeah, i have only 2 thought about the mod, need to buff a little the dragon claw and the gauntlets.....and maybe add the Spikes Balls/Red Rain who were really a good thing in heretic?

Awesome mod and system again!
