Old Rex
Level 110 · Boss · attacks on sight.
“The valley's end, and its oldest thing, on his throne up on the high plateau. An arrow is best (40% more from archery), a sword gets 60% through, spells do nothing, and he roars stones down six tiles. Anyone who hurts him shares the kill.”
An open boss: it belongs to nobody. Everyone who does their share of the damage (5% of its health) gets their own kill and their own drops, and a report when it falls.
Its own pet, Rexling: about 2% of kills.
