I already know skills slightly increase depending on your stats, for example Orison of Healing is related to Healing Prayers. My question is, is there a way to upgrade these skills? Like in World of Warcraft for example, you could get Ambush 1, Ambush 2, Ambush 3, etc...
Some of the elite skills are similar to normal skills but act as an upgraded version - that's as close as it comes. Example: Life Siphon and Life Transfer.
ayup, by pumping more into a skill line, the skills would naturally evolve like wow's ambush 1, 2, 3, etc. By pumping your skill line you could in effect get like an ambush 5-6. Just pump more attributes into that line you're focusing on.
