Rolling a 20 will mean something again!

I am thinking about expanding the natural "20" to do something cool every time it is rolled.

Here are a few ideas.

Clerics
HOLY Healing Strike!!!!! Heals 1d6 HP per level to all friends within Wis in feet and damages all undead.

Fighting Men
Fighters get the Critical Hit ability. When they roll a natural “20” they automatically do triple damage. This damage continues to cleave to the next monster if the first one dies from the massive damage. Critical hits improve to x4 at 4th level x 5 at 8th level improving every 4 levels.
EXTREME DAMAGE!!!!


Magic-Users
RECHARGING BLAST!!!! Spells are recharged? I will have to think about that.

Thief
KNOCKOUT STRIKE!!! or BLEEDING or SLOWING

Assassin
EVISERATION!!! Save or die.


Barbarian
Their Critical hits go up every four levels like Fighting Men every four levels but start out at only x2 damage.
KNOCKBACK STRIKE!!! All victims that don't die are thrown back 5ft per +1 of Strength.


Bard
EMOTIONAL/INSPIRED BLAST!!! Everyone gets a free attack and +2 to hit


Druid
NATURAL FURY!!!! Storm clouds burst around Druid doing 1d6 a level in Wis radius damage to all enemies.

Monk
FLURRY OF BLOWS!!!! Monk gets 1d6+Level hits.

Noble
COMMAND AND MOVE!!!! Everyone gets a free movement and attack and +2 to damage

Paladin
Their Critical hits go up every four levels like Fighting Men every four levels but start out at only x2 damage.
DIVINE STRIKE Any unholy or undead creature must save or die.

Ranger
Their Critical hits go up every four levels like Fighting Men every four levels but start out at only x2 damage.
FLURRY!!! Many dual weapon attacks or many Arrows fly

Sorcerer
EXPLODING!!! All enemies within Chr range take 1d6 per level.

Spellblade
Their Critical hits go up every four levels like Fighting Men every four levels but start out at only x2 damage. +1 to hit every 4 levels. 8HP+1d8HP a level.
MAGIC BLADE BLAST!!!!!All enemies within Int range take 1d6 every 2 levels.

Wanderer
Their Critical hits go up every eight levels but start out at only x2 damage.
LUCKY TO EVERYBODY!!! Everyone gets to roll 2 dice and pick the best.
