My forge is level 10 and my stronghold is level 17.
I use mana potions and bear banners for challenges and titans, arrows and axes for bosses.
Plus a smattering of turtles and health potions.
My alliance is quite young and we fight 3 and 4* titans. I have a 2800 team and normally score in first or second place. I usually play Kiril to buff my team.
Is there any reason to progress the forge?
