Gemling Explosive Grenade

Explosive grenade fires 1 projectile while having 14% quality and Advanced Thaumaturgy active.
The tooltip also says Projectiles fired 1
Either description or quality interaction is incorrect

also having this issue

instead of +2 to projectiles, skill has line "2 projectiles" from alt quality.
fix please

the same thing happens with plasma blast, it only fires 2 projectiles at 26% quality despite saying it fires 2 extra from gemling which should be 3 total but it doesnt work. Its fun how gemling doesnt really do the one thing he is supposed to do xd.
