Paladin

Major

• Glyph of Holy LightLevel 15Your main heal also heals the allies around the target: a huge gain, though it does not carry over through Beacon of Light.
• Glyph of Seal of WisdomLevel 38Mana is your only limit: this glyph lowers the cost of all your heals.
• Glyph of Beacon of LightLevel 60Beacon of Light lasts longer: less time and mana spent recasting it.

Minor

• Glyph of Lay on HandsLevel 15A shorter cooldown for your biggest life-saver.
• Glyph of Sense UndeadLevel 201% more damage against the undead, at no cost.
• Glyph of Blessing of KingsLevel 20Blessing of Kings costs half as much mana when you need to rebuff in combat.

Other choices

• Glyph of DivinityLevel 15For fights where mana runs short: cast on yourself or another healer, Lay on Hands restores a lot of mana.
