About Castelune
Every round you look after two things: your castle and your army. The castle stays home. A wall stands in front of it, and behind it you build up five buildings: a cannon that fires on attackers, a treasury, a forge, a war banner and a witch's cauldron. Each time one of them levels up, you choose one of three upgrades. The army goes out. When the build phase ends, it meets a rival's army in the field, and the winner marches on the loser's castle.
Put too much into the castle and your army falls behind. Put too much into the army and the next siege hurts more than it should. Most of the decisions in a match come back to that. Units, items and heroes44 units across five rarities. Merge duplicates to level them up. The forge turns iron into items. You pay, look at three and keep one. Every unit has four slots: head, chest, feet and weapon.XP books level a unit up without needing a second copy.
You get them from the banner and from treasure chests. At the start of the match you pick one of six heroes. Each one pulls your game in a different direction. SynergiesSeven races and eight classes. The class decides what a unit does in a fight: warriors make enemies bleed, mages burn or chill them, hexers curse them and rangers mark targets for everyone else.…
