How does the Bomb Specialist bonus work?

The only time the player has traps is when they're placed in the world. A number of cooldowns on a trap skill is not a number of traps.

This is supposed to be worded exactly as the bonuses per minion, but I've discovered those were changed after the point those descriptions were finalised, without being re-checked. Fixing this is on my to-do list, but may not make it into the initial ascendancy patch.
