I've played stealth games before, I recognize these when I see them:
- Standard bolt
- Frog bolt for underwater use
- Crystal bolt, freezes foe in magic crystal
- Leaf bolt, lays out a soft surface to muffle sounds
- AP bolt, for heavy armor targets
- Fire bolt
- Noise maker
- Homing bolt
- Grappling hook for climbing
- Tree bolt, grows trees anywhere you need them
- Stun bolt, knocks foes unconscious
- Water bolt, splashes torches to douse them
