After some spearman playtest here's how I see it:
- Barbed spear: increase dmg from 55-65 to 65-75. And it will be fine.
- Snake spear: increase dmg from 20-130 to 70-130 (probably even 100-130). Change first perk from Bonus Damage to Piercing Strike. This variant needs to be tested, because now quite hard to say precisely if it will be OK.
P. S. Btw Barbed spears with 10 Luck now are quite efficient, in some cases better than Serrated spears, delivering about 50 dmg + 80 bleed with groin hit.
