Quick answer
  • Use this as a checked name-and-effect reference, not a complete unlock chart. The official rune listings confirm the abilities below and their class requirements. A rune granting four ability levels does not tell you the skill’s base damage, unlock level, Mana cost or full behavior.

The Blood Strike/Bloodblade wording is preserved because the official item name and effect text differ. It is not enough evidence to declare two separate abilities, or to silently rename the effect.

Ability changes worth recognizing

Selected 1.0.2 changes, with the 1.0.2a trap update
AbilityWhat changed
Ice ShardsBase Cold damage rose to 115%; each additional ability level adds 3.5 percentage points.
Flame LightningIts Fire and Lightning portions each rose to 60%.
Arcane TrapIn 1.0.2, Frost Trap became Arcane Trap, dealing Arcane damage and applying a five-second Arcane Grip. Hotfix 1.0.2a says it now applies Dizzy, reducing attack speed and benefiting Flare.
Golden PalmsBecame a traveling projectile that passes through enemies; casting range rose to 2.4 units.

These patch entries describe selected changes, not full tooltips. The Ice Shards entry does not state its Mana cost. The five-second Arcane Grip description belongs to 1.0.2; the 1.0.2a hotfix does not give a Dizzy duration or establish every immunity or resistance interaction.

Separate the ability from what modifies it

A base ability, a talent that triggers another cast and an item that replaces an effect are three different parts of a build. Vessel of the Endless Stream is a clear example: its Black Mist effect removes Spirit Stream’s healing and makes it deal nearby Lightning pulses instead.

Read the active item and set effects alongside the skill. Otherwise, a clip showing a triggered spell or a changed skill can look like a different base ability. In ordinary combat, patch 1.0.2 also starts a newly equipped ability on its full effective cooldown; swapping it is not a free instant cast.
