Hated and feared throughout time and space. Nightmarish alien creatures in bonded polycarbide armour. They seek to exterminate all non-Dalek lifeforms.

If you're using modern or advanced tech in your game as 'magic' then I'd suggest the Dalek can absorb up to 100 points of damage from ranged attacks each round.
