The skill description of Heart Rune Energy (498612) says:
EN - Restores (DMG1) HP to friendly targets. Also increases caster's [SC_SKILLTIPS_MND|Wisdom] by (Buff4-0)% for (Buff4-Time) seconds.
DE - Stellt bei befreundeten Zielen (DMG1) LP wieder her. Erhöht außerdem die [SC_SKILLTIPS_MND|Weisheit] des Zauberwirkers um (Buff4-0)%. Hält für (Buff4-Time) Sekunden an.
In fact, it only heals the target but no other player.
Please change the skill like it is intended to work
