Glyph of Moonfire

The Glyph of Moonfire shifts the damage of a druid's moonfire spell so that the initial damage is inconsiderable but the damage over time is much higher. It results in an increase to the spell's total damage, but removes the instant burst damage. Because the damage over time component is more powerful, it pairs well with a Glyph of Starfire which increases the duration of Moonfire's damage over time by three seconds when Starfire hits.

Calculations
These numbers are here to help you choose whether or not to use this glyph. They are based on max ranks for a level 80 (WotLK) Balance Druid. Your moonfire spell deals instant damage of [ 435 + 15% spellpower ] and applies a dot of [ 200 + 13% spellpower ] per tick. When the Nature's Splendor (druid talent) talent is active, you deal, without the glyph, a total [ 1435 + 80% spellpower ]. With the glyph, you deal a total [1750 + 112% spellpower]. The DPS increase from this glyph is thus about [ 21 + 2.1% of spellpower] per second. For someone with 3000 spellpower, this would mean around a 84 dps increase (discounted from all damage buffs, debuffs and talents). For comparison, Glyph of Insect Swarm grants a damage increase of about [ 30 + 3% spellpower] per second.
