I like to swap between elemental charge blades to hit the monster I'm hunting's weakness, but some of them are much weaker than others despite being fully upgraded or almost fully upgraded. This also buffs the elder dragon weapon's (Zorah Magdoras only gets minor buffs as it's easy to get) to be more fitting of having come from an elder dragon. Xeno'jiiva in particular was...very disappointing when I first saw the vanilla values. Hidden elements have been buffed highly, and assumes you are still using the vanilla Free Elem / Ammo Up skill values (33% with one level, 66% with two, 100% with three), otherwise it will be easily overpowered. Not all Iceborne weapons have been covered, as I have yet to get to it myself and have no personal experience with it. I will probably need to nerf some of these as I'm a casual player and don't understand the metagame at all, but I'd figure I'd go ahead and throw it out there to get some feedback. Requires Iceborne and Fatalis update.

Compatibility: Mods that directly edit the charge blade's data values (or the c_axe.wp_dat file) will conflict, as either this mod or the other mod will completely overwrite the other. If you wish to edit the damage values yourself, you need to multiply the damage shown in the monster hunter editor by 3.6 (specifically for the charge blade, other weapons have different multipliers) to get the value shown in game (eg, shows 180, 180x3.6=648 damage). Elemental damage is multiplied by 10 (shows 23, shown value is 230). 

Don't sell this mod or stick it behind a paywall, otherwise do as you wish with it.
