Does pure damage 1x. Simplest type of gem.
Does pure damage 3x. Great in combination with rage, or against people using Ice.
Does pure damage 1x. Shields take 3x damage. Ignores reflect and block.
Once you build up enough lightning damage, stun for a round and decrease total stun by that much. The amount of lightning damage required to stun an opponent increases over the duration of a level; the first round of stun costs 4 lightning, next 10 lightning, then each subsequent stun another 10 (4, 10, 20, 30, 40).
Does N points of fire damage at the beginning of the turn, then decreases N by 1. If an attack deals 5 points of Fire damage, it'll deal 5 points next turn, reduce to 4, then do 4 points next turn, etc.
Blocks N% of damage received until end of combat.
Blocks the next N points of damage.
Damage dealt is reduced by ice points, and ice points are reduced by 30% for every attack. So if you had 10 points of ice-damage, and did 50 points of damage, you'd do only 40 points of actual damage (-10 removed by your ice points), and ice points would be reduced to 7.
Poison damage is dealt only at the board shuffle (end of a 'round') and ignores shields.
Adds an additional +X points of damage to any subsequent attacks/hands(including combinations that would normally inflict no damage, such as Shield and more Rage). Rage is reduced by 10% each round, including the turn on which it is cast.
Increases the amount of Rage by X every turn. Effect is not available to the player.
For the next N turns, reflect all damage back at dealer
At the turn start, regenerate 10% of total HP. Continues for N turns
Your attacks do -25% damage for the next N turns
