Well thats the 3rd and final grot ninja completed just 1 more to go and that will be all my objectives completed.
As I mentioned before these guys are the rebellion scouts they find the enemy and call in the main force. I enjoyed doing a base with a some life compared to my usual dry deserts and ruins.
Whether the grot ninjas return in the future to fight for the rebellion (with the exception of grothopper representing marbo) will depend on if any good assassin units are featured in the rumored codex Inquisition.
Though I may choose to repaint him soon.
