Warning: Long.
Some useful quotes for avangions:
Rather than becoming a fearsome dragon, however, the pre- server emerges as a beautiful, fragile creature that looks much like a gossamer- winged butterfly. This process is also extremely painful, but the avangion gains in Wisdom rather than falling prey to savagery. (defilers and preservers 38)
Each class metamorphoses into a different advanced form. Defiler/psionicists become drag- ons. Preserver/psionicists become avangions, ex- tremely delicate creatures of tremendous magical power. A defiler or preserver cannot advance past
20th level without becoming an advanced being. (dragon kings 9)
The transformation requires a similar process, a series of steps that lead from human to avangion, but whereas the defiler/dragon metamorphosis is characterized by massive destruction and great pain, the preserver/avangion blend is a more se- rene, peaceful process of light, water, and the life- giving properties of a dying world. (dragon kings 42)
In his present state, Korgunard can be used like a tree of life by the defiler to
charge his defiling spells (arcane shadows some page. there are no page numbers in this section and Iām not counting).
speaking of arcane shadows Korgunards transformation involves water and ends up creating a bunch of plants. (that said, in general I take arcane shadows with a grain of salt)
Mitigating factors:
2e stage 1-3: isolation period at 75% xp, must gain 25% xp alone: the preserver must spend the isola- tion period gathering physical remains of the ene- mies of life, usually those of high level defilersĀtheir bodily remains, destructive belongings or artifacts, ash from their spellcasting, etc. These items are evi- dence of devotion to life and the land. The spell must then be cast at night, beneath the light of both Athasian moons. The casting time is six hours.
2e stage 4-6: complete isolation at 75% xp, must gain remaining xp without contact with any creature that is not a foe to be defeated. The material components at the middle levels are gifts gathered from no fewer than three powerful good creatures during isolation. The powerful crea- tures realize the consequences of contact for the pre- server, so they leave the gifts to be found after the preserver achieves extremely dangerous or impor- tant goals.
The material component for the spell (not con- sumed in casting) is a single tree or bush personally saved by the preserver from defiler magic destruc- tion. The casting time is 12 hours. At the time of casting, there must be living vegetation for at least one mile in all directions, untainted by defiler ash or evil creatures.
2e stage 7-9: must gain final 25% xp with up to 8 10+ level good companions.The material components are a single gift from each of the companions in the core group. During the casting of the spell, the preserver must have the aid of a single companion for the entire length of the ceremony. If the companion is not ab- solutely good, the spell fails and the companion is slain in the release of failed magical energy. Com- panions cannot repeat the process with a single preserver
2e stage 10: To cast this spell, the preserver must make an area of lush vegetation (crops, scrub- grass, forests, or any combination) at least five miles in diameter. The preparation time for the spell equals the time it takes the preserver to create these lush lands. At the time of casting, the lush lands must be free of evil creatures.
The material components for the spell are a dia- mond of no less than 10,000 gp value with which to capture the life- giving qualities of sunlight, a stone tomb large enough to hold the preserverĀs body, and a perfectly sealed glass case built around the tomb. The casting time is one round. Upon casting, the preserver/avangion, diamond, and stone tomb dis- appear, bound for planes unknown. The DM then secretly rolls 2d12Āthis is the number of months before the return of the preserver, in final avangion form, to the glass case. If the glass case is damaged in the meantime, the avangion is lost to oblivion.
3e made Avangions have focus structures of a sort, and used the companion part of the 7-9 spells to add 8 additional casters contributing 5th level spell slots. Final stage had a huge ad-hoc reduction based on the 2e version.
If youād like I can try to do a statistical breakdown of what I feel the spells should give them overall and add in suggestions based on my own thoughts on what powers it might give that were not in the 2e or 3e version as well as what I find weird about both.
Edit: Also, from the 4e epic destiny: You feel the pulse of the world and hear the whis- pers of its spirits. Your soul keeps you in a constant meditative connection with creation. The life force of Athas weaves its threads into your being, linking your mind, body, and soul with the world. Using this connection, you can alter your mortal form to become a bright, winged spirit.
