The general idea would be to have the kit create mechanical toys oriented towards your race, but they all do the same things, just their appearance that changes, such as: Asura: Golems. Norn: Mechanical animals based on the 4 spirits. Charr: Siege-weapons oriented toys. Sylvari: Nature-related designs, such as oakhearts.
Now for the skills: X being the race-related design
#1: Auto-attack: X Grenade: Throw a toy at the enemy which explodes on contact.
#2: Mini X: Drop a small toy on the ground with wheels that rolls towards the target and explodes on contact and cause a small AoE around it. Can’t be targeted. Cause 1s cripple. Blast Finisher.
#3: X: Drop a character-sized toy on the ground with wheels that rolls towards the target and explodes on contact and cause a larger AoE around it. Can be targeted, explodes where it dies if killed. Blast Finisher.
#4: Decoy: Drop a mechanical toy statue representing your race that can be attacked and stays alive for 10s and shares your armor/toughness. Go in stealth for 3 seconds, gain vigor boon for 5 seconds. 25s cooldown.
#5: Last Resort: Send out #1, #2 and #3 at once.
#Toolbelt: Red Button: Get knocked back by an explosion (Similar to Elixir Gun’s 4’s effect) while sending out 3 #3 skill at the target.
