The special fights in Guildrun
Fight events are the Guildrun combats that ask for something other than a win. Some count the damage you deal, some ask the guild to survive, and one puts a single hero up against a single enemy.
Each one pays out in tiers, so beating the first target is worth Shards and reaching the highest target is worth far more, and even a loss pays something.
