I'm working on making 4th edition a grittier and more taxing version of itself. My goal is to make combat more dangerous with few additions.
What do you guys think of...
1. If a creature takes more than CON damage in any single HIT, they must roll a CON check greater than the damage taken or be Dazed (save ends).
2. If healed from Dying (negative hit points), a creature is immediately Stunned (save ends).
3. Subtract 1 hit point per level off every class.
4. On a critical hit, extra damage from things like Sneak Attack and Warlock's Curse are rolled and not maxed.
5. Death Saves are reset only from an extended rest instead of short rests.
It's supposed to be a low magic world so I'm also thinking about things like... arcane casters needing to take a minor action to Channel before casting a spell, and if not the spell does damage the caster equal to twice it's level. (And similar things for the other casters). To offset this flavor, I'm thinking about giving DR to the Heavy Armors but saying that magic sources circumvent that. My standard DR of 1/2 level to minions rule would apply.
These are just ideas. Do you think that any of them are just morbidly over the top and would kill a party at whatever level?
