Don't have a lot of time today, so i'll tackle glyphs.
You can have 3 prime, 3 major and 3 minors. The ones i use are below.
Glyph of Death Coil - Increases damage and healing of DC by 15%. Since DC is always in the top 3 moves for damage this is a huge dps increase. Plus it also helps with DC heals via Lichbourne.
Glyph of Raise Dead - Your Ghoul receives an additional 40% of your strength and 40% of your stamina. This is huge for you pet because he counts for about 30-40% of your damage. Also more stamina will make him harder to kill.
Glyph of Scourge Strike - Increases the shadow portion of scourge strike by 30%. Although your more likely going to use Necrotic Strike for damage, this will help increase your burst for when using NS will be useless.
Glyph of Anti-magic Shell - Increases the duration of Anti-magic shell by 2 seconds. This doesn't sound like a lot but its huge! The more time your not taking magic damage the better. Can also be used to avoid spells like Ring of Frost and Ice trap.
Glyph of Strangulate - Increases the duration of your Strangulate ability by 2 seconds when used on a target casting a spell. This is huge! Strangulate is already 5 seconds, so a 7 second silence could be game breaking.
Glyph of Death's Embrace - Your Death Coil refunds 20 runic power when used to heal. When healing your pet or yourself with Lichbourne this will give you enough RP back to keep the heals going. Well worth it. Also not many other choices for pvp.
Thats it for now, stay tuned for more DK notes soon!
