From Guild Wars 2 Wiki
— In-game description
- While Transfusion does attempt to heal you, being in Death Shroud prevents you from gaining health from any source; if Life Force runs out during Life Transfer's channel, Transfusion will heal you.
- The amount healed does not scale with the amount of targets hit by Life Transfer, and in fact, the heal occurs even if no targets are in range.
- Teleport range is a static 600, but the healing and revive range is limited to the normal range of Shroud skill 4.
- If a downed ally is affected, Transfusion does count as reviving someone for Ritual of Life.
