[Champ concept] Aggon, the Prismatic Sorcerer
Aggon is a mage intended for the midlane. He wears a light blue robe and he has no staff or weapon, instead prismatic crystals circle around him like Syndra's balls.
Not providing any stats, but he's supposed to have pretty normal mage stats. Also take any numbers with a grain of salt, I'm not good at balancing xD
Lots of reading is required to understand this crappy concept. Q will be leveled up automatically at level 1!
Passive - Prismatic Crystals
Aggon gains 10% (+ 10% per 100 AP) attack speed if he has 1 or more prisms. His normal auto attack is a magical bolt, but if he has prisms, he fires his prisms instead. On towers, wards, etc he does not use the prisms. (Auto attack range is 550. Also, his auto attacks travel pretty fast, like an adc)
Q - Prism Enchantment
Cost: 30 / 35 / 40 / 45 / 50 Mana CD: 2 Seconds
Channels for 0.75 seconds to create 3 prisms. If interrupted, Aggon creates only 1 prism instead. He can have up to 6 prisms. If Aggon has at least 1 prism when using the ability, all his prisms are powered up by 1 stage, which changes their color. (3 is the highest possible stage, stage 1 is green, stage 2 is yellow, stage 3 is red). If Aggon has no prisms when using the ability, his prisms start out at stage 1. After 6 / 7 / 8 / 9 / 10 seconds of not auto attacking, Aggon's prisms go down to stage 1.
Aggon's auto attacks deal 20 / 30 / 40 / 50 / 60 (+ 20% AP) extra magic damage at prism stage 1, 30 / 45 / 60 / 75 / 90 (+ 35% AP) extra magic damage at prism stage 2 and 50 / 80 / 100 / 120 / 140 (+ 50% AP) extra magic damage at prism stage 3.
W - Crystal shield
Cost: 50 / 60 / 70 / 80 / 90 Mana and 1 prism CD: 12 / 11 / 10 / 9 / 8 Seconds Shield: 50 / 70 / 80 / 90 / 100 (+ 30% AP) Duration: 2 seconds with a stage 1 prism, 4 seconds with a stage 2 prism and 6 seconds with a stage 3 prism.
Aggon uses a prism to create a crystal around himself that shields him. Higher prism stage means longer shield duration.
E - Magical blast
Cost: 60 / 75 / 90 / 105 / 120 Mana CD: 10 / 9 / 8 / 7 / 6 Range: 1000
Shoots a large sphere in a straight line that explodes on the first enemy champion hit, dealing 50 / 70 / 90 / 110 / 130 (+ 40% AP) magical damage and applies magical mark to the enemy for 6 seconds. Aggon's next auto attack on the marked target consumes the mark and stuns the enemy for 0.7 / 0.9 / 1.1 / 1.3 / 1.5 seconds.
R - Crystal explosion
Cost: 100 / 125 / 150 Mana CD: 160 / 145 / 130 Seconds Explosion radius: 600
Aggon explodes, dealing 250 / 300 / 350 (+ 75% AP) magical damage in an area around him. He then takes form of a magical cloud that nobody can interact with, for 10 seconds. In this form, Aggon can not take damage and he can not attack, cast spells or use items, but he can move around. After the effect is over, he transforms back to his normal body.
So yes, that's my champ concept. His gameplay should be like that of a battle mage and he uses auto attacks for his damage. Recommended items are RoA and Nashors Tooth. The mechanic of his Q should be really interesting, because he has to charge it up all the time. He has to time his casts well to get a good amount of prisms and then throw them on the enemy. An important strategy is to stop attacking if you have only 1 prism left so you don't reset the prism stage during a fight. His ult is a really powerful tool to deal damage and to escape.
All in all I'm pretty happy. Let me know what you think. :)
