Demolitions (Wasteland 2)

Demolitions is a skill in Wasteland 2.

Wasteland 2
Allows the player to arm and disarm a variety of different explosives. This skill is primarily used to deactivate booby traps.

The perk "Long Arm" (which is firstly unlocked after Demolitions level 2 and then secondly activated after spending a perk point) improves the range that you can throw explosives, such as grenades, pipe bombs etc. While damage is NOT improved with additional ranks in Demolitions, the distance thrown is improved with the above perk. At Demolitions level 6 the "Bomberman" perk, which is unlocked in a similar fashion as "Long Arm," further improves the utility of explosives in combat by improving the AoE (area of effect) of the explosives. Long story short while it is true that your skill rank in Demolitions does NOT change the damage of explosives, it DOES change the relative accuracy and utility via the ability to land bigger, more precise/long range explosives in combat.
