Support spells: what you give
Your shields grow with Charisma and Healing Power. Your buffs do not: they give the same amount whoever casts them.
Shields
Healing power = Charisma x 0.5, raised by your Healing Power percent from gear, skill nodes and stacks.
Shield = healing power x the multiplier, rounded up. It fades to nothing over 3.5 seconds.
The table shows the shield with no Healing Power at all.
| Source | Who gets it | Multiplier | Charisma 20 | Charisma 40 | Charisma 60 |
|---|---|---|---|---|---|
 Barrier | on one ally | 5.44 | 55 | 109 | 164 |
 Devour | on you, when it kills | 5.44 | 55 | 109 | 164 |
 Shielding Inferno | on allies in the fire | 3.5 | 35 | 70 | 105 |
 Warding Void | on allies inside when it collapses | 3.5 | 35 | 70 | 105 |
Where to get Healing Power
5 rune sets can roll it.
Buffs
Circle of Magic: +25% magic damage for everyone standing in the circle, you included. The circle lasts 10 seconds.
War Banner: +20% physical and magic damage near the banner, you included, for 15 seconds.
Its text says 15% Stamina regeneration. The game code does not read that number: while the banner's effect is on you, your Stamina regeneration is multiplied by 2.
Who each support spell can affect
| Spell | Who it can affect | Cooldown (s) |
|---|---|---|
| Barrier | Allies only, not you. | 16 |
| Circle of Magic | You and your allies. | 20 |
 Combat Medic | Allies only, not you. | 12 |
 Rejection | You and your allies. | 12 |
| War Banner | You and your allies. | 45 |
Thrown flasks
A thrown flask also works on you if you stand where it lands.
Healing Power does not change what a thrown flask restores.
