In the rules for critical damage if you take 10 crit damage then amunition explodes in some of the cases dealing 1d10+5 damage. This in effect killing of the group of players when they charge in with all weapons that cause either energy damage or explosion damage.
This poses a severe problem for characters that deal allot of damage but is a bit squishi on the damage taking side like the assasin or the psyker.
Anyone got any ideas on how make the effect not as prominent to kill of large parts of the the PC group.
