By my calculations, the orc decisively passes the elf at only 480 conversion points, without the Tri-sword
480 is 4 conversions for the orc, or +10 base damage. With a trisword that would be +14 base damage.
480 is just
shy of 7 conversions for the elf, which with your trisword would result in +7 mana and +7 attack.
This so horrendously favours the elf to the point at which it virtually renders the Orc obsolete. Without a trisword the orc is barely ahead at all, and even with it the comparison is 7 mana / 7 attack versus 14 attack. Unless you have a huge attack bonus, the elf is way
ahead here, to the point of rendering the orc obsolete.
If elves get better because of the Tri-sword, they don't have to stay at 70 conversion points.
Oh, so you're suggesting making the entire race
less powerful to compensate for a single overpowered item? No, the whole reason the Trisword has a problem right now is because
it favours a specific race.
Blood mages are hard to level up with, because of their lack of resources to fight high level monsters. This is the advantage of using an elf

item for bloodmages that gets them through that rocky early game. Can't beat anything for bonus XP? Just keep blasting as you explore and you'll eventually topple your target.
