Avangions (DK)

__TOC__
In the entire known history of the Tyr Region there has never been a preserver who has advanced far enough in experience to mimic the metamorphosis of rival defilers. But it is possible. 
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 serene, peaceful process of light, water, and the lifegiving properties of a dying world. 
Prerequisites: Only humans can proceed through levels from 21st to 30th as an avangion. Also, the ability score requirements are stringent: A preserver passing 20th level must have an Intelligence score of 18, Wisdom 17, Constitution 15, and Charisma 16.

As with dragons, avangion level advancement is a two-part process. The avangion must first earn the experience points listed for its next level, then successfully cast the avangion metamorphosis spell. (This spell is the first psionic enchantment cast by the character, who can cast it to advance from 20th to 21st level, even though technically the spell is unavailable before 21st level.) Points rolled on Hit Dice are rolled add directly to the avangion's hit point total; Constitution modifiers are added per die rolled. 
==Avangion Metamorphosis Spell==
The avangion metamorphosis spell describes the procedures for accurate casting. Deviations or outside influences that cause the spell to fail do not result in the caster's death. Instead, the preserver or avangion's experience points are reduced to the minimum of its last level; it cannot attempt to advance until it has re-earned those experience points. 
Unlike the equivalent dragon spell, the avangion metamorphosis spell sometimes calls for a period of isolation for the caster. If the spell is successful, it returns to its companions in the next step of the conversion, each time closer to its magnificent final form. 
Like dragons, avangions are effectively immortal. Avangions also have four spell-like abilities permanently active: tongues, know alignment, ESP, and detect lies.
21st-level avangion: This first stage of the change from human to avangion is very subtle. Its physical appearance changes only slightly—more noble features to its face and a silver or golden sheen to its eyes. Armor Class is reduced to AC 9, and the process grants a magic resistance of 10%. The avangion's THAC0 falls to 10. 
22nd-level avangion: At this level, the sk in takes on the metallic glow of its eyes and the hair turns bright white, but the character is still quite human in appearance. AC improves to 8. Magical protections give magic resistance of 15% and immunity to weapons that aren't of +1 enchantment or better. THAC0 remains 10. 
23rd-level avangion: Any concealment of the character's true form is lost with this level and the sprouting of enormous gossamer wings from the back and shoulders. The wings themselves, Blmy and nearly transparent, span 20 feet. The eyes become bright silver at this stage, and the skin glitters in the sun light. Its newfound wings let the avangion fly with MY 24. AC improves to 7 and magic resistance to 20%. THAC0 improves to 9. 
24th-level avangion: Now well on its way to true avangion form, the character's original human appearance is increasingly vague. All hair vanishes from the body, and webs of filmy wing-like material form between its arms and torso and its fingers and toes. Its existing wings form multiple folds but can be extended to a 25 -foot span. The avangion's natural Armor Class improves to AC 6, and its magic resistance becomes 25%. Also, it can only be hit by weapons of +2 or better enchantment. The avangion's THAC0 remains 9. 
25th-level avangion: With this level the avangion's human form decreases drastically, becoming lost in the wispy folds of its wings, which can now extend to a 30-foot span. The character's jaw retracts and its eyes grow on its oval head. Its arms and legs grow far thinner and can no longer support its weight-the character can no longer walk, but instead floats and flies at all times. The character can no longer wield hand-held weapons or make any physical attacks of its own. However, the avangion's magical nature continues to improve. Armor Class becomes 4, and magical resistance rises to 30%. THAC0 becomes 8. 
26th-level avangion: The avangion becomes a far more mobile yet graceful creature. Its incredible, shining wings now span up to 40 feet, with its central body nearly lost in their folds-the avangion can now fly with a MY of 36. AC improves to 2, magic resistance becomes 40%, and only magical weapons of +3 or better enchantment cause it damage. THAC0 remains 8. 
27th-level avangion: The character's original human form is nearly lost. The creature has only a torso and head, nearly lost in the endless folds of its gossamer wings that now span 50 feet when fully extended. The avangion's increasingly magical nature gives it AC 0, 50% magic resistance, and immunity to weapons of less than +4 magical enchantment. THAC0 becomes 7. Also, enlightenment associated with its incredible power gives a +1 bonus to its Wisdom score. 
28th-level avangion: The avangion first takes on its aura at this level, a radiance of brilliant light that extends 90 feet from it in all directions. The aura acts as a permanent protection from evil spell and dispels all magical darkness within it. The avangion's wingspan increases to 65 feet, and its movement rate improves to MY 48. Only weapons of the finest enchantment, +5, can strike the avangion's physical form. AC improves to -2 and magic resistance climbs to 60%. THAC0 remains 7. At this level, the avangion receives another +1 bonus to Wisdom. 
29th-level avangion: The aura grows to a 150' radius. In addition to previous effects, the aura acts as a ray of enfeeblement on all evil creatures within it. Armor Class improves to -4 and magic resistance to 70%. Physically, the avangion grows still more—its wings, now with an 80-foot span, nearly envelop its torso and head. From a distance it appears as a cloud of interwoven wings. The Wisdom score increases by 1 at this level. 
30th-level avangion: Now in its final form, the avangion's cloud of overlapping wings can extend to 90 feet. The incredible aura extends to a 200' radius and, in addition to existing effects, acts as a permanent globe of invulnerability. Mobility increases to MY 60, Armor Class to -6, and magic resistance to 80%. At its final stage of transformation, the avangion gains an additiona 12 points of Wisdom. 
Regardless of level, an avangion saves as a 21+ -level wizard. 
===Role-playing an Avangion===
Avangions go through no animalistic stage and never lose their mental faculties. On the contrary, as an avangion progresses through the metamorphosis, its intellect increases, marked by the increases allowed for its Wisdom score (to a maximum of 25). 
The avangion is the first of its kind in recorded history, a focus of change toward good, the most powerful good character that a. player can have. 
Naturally, avangions and dragons are arch-enemies who plot endlessly against each other's interests. 
Advanced beings are extremely powerful, but large numbers of lesser creatures can still bring them down. The downfall of dragons is their inability to work in a team. In contrast, avangions will certainly attract followers in campaign play, though they must leave these people for intervals during their metamorphosis.
