Group Attack
From Fallen Sword Wiki
Group attack is a means with which to kill much stronger enemies, champions, elites, etc. It can also be used to capture relics, etc.
The basic concept is that you take the group leader/founder's strength, then add 20% of each person's stats to the group stats, so your strength comes out as follows:
Self = 100% Self plus 1 = 100% of self plus 20% of player 2 Self plus 2 = 100% of self plus 20% of player 2,3 etc. etc.
The cost to create a group is 20 stamina The cost to join a group is 5 stamina
No gold costs are involved!
The guild gets the gold from the attack, and the experience is divided among the main player who gets a little more credit, then distributed equally to each member of the group.
