Team cost 30 - brought 10 mini mana but didn’t use. Stacked with 2 (!) Aifes, so no way I could lose!
CRen was the main damage dealer and did a great job mana controlling the bosses, staying filled on mana even when there were no purple tiles; this also meant I could send off-color cascades without much fear to work the board to purple. Gil-ra did a nice job of softening them up and blunting the boss hits. I took Bjorn to hit them hard, but he was the first leveled hero to die, so all he really contributed was getting me to the final stage with minimal damage, as he nuked mobs in stage 1 and 2.
In all seriousness, the Aifes were quite useful in the first level as disposable damage sponges. The hits they took didn’t affect the heroes I was invested in, allowing me to survive. It also meant that I had another color of tile damage, even though it was minor, so off-color cascades did some minor damage.
This was fun and helped me save even more heroes for later in TOL.
