1. They need to get Bolt Creation like Artificer. 1 Tier Enhancement, or Second Core Ability would be good for them.
*Really needed... even Conjure Bolt Scroll is still bugged to use... and tangle foot is I think useless.

2. on Live Version, Insightful Crossbow damage is at level 6 mechanic. but on Lammania, It's at level 12 mechanic.
*I heard devs will fix this. they said being that much high is not intended.

3. Rogue's Opportunist feat(Double strike +3%) should get double shot.
*Devs should forgot this maybe...
