I'd like community help! Got an idea for a lizard type champion.

Please need input on a champion idea i have that i just can't get down to words. Name Sala (like salamander), fire of depths.

Basics of Lore: an ancient being who controlled the flow of magma. Was imprisoned by Atlantian High Council for his crimes against the land. Was a royal guard for the nobles. His family was enslaved after not paying the high taxes of the nation. He broke them out and hid in the deep volcanic caves of the ocean trenches before he was imprisoned and his family was murdered.

Passive: Magma Armor - Any time Sala's 'Fire Breath' hits a target sala gains a mark of Magma armor. After he reaches a stack of 7 marks, Sala can set himself on fire burning any enemy that attacks him, for 10% of their missing health for the next 3 seconds. While The target is being burned, their armor is reduced by 5% each second. Magma Armor Fire last for 7 seconds and can apply the debuff to the same target multiple times while it is active.

Q - Fire Breath - Passive - Sala builds up a super heated breath as he walks and attacks enemies to max charge of 100. (1 step equals 1, 1 basic attack equals 20) For every point in the charge Fire breath deals 1.25 additional damage.

Active - Sala releases a super heated breath of air that deals 55/70/85/100/115 magic damage.

W - Pressurized Tunnel - Sala creates a path from himself to a target location that an ally can use to gain a 40/45/50/55/60% movement speed dash toward Sala's location. Sala can have a max of 2 tunnels active at once. Dash only works if ally champion is walking toward Sala.

E - Catch/Release - Sala shoots his long tongue forward in a line. If his tongue hits an enemy champion, Sala wraps his tongue around them and pulls them to his location. If activated within 2 seconds he can then throw them the same amount of distance in a different direction. While wrapped up in Sala's tongue (2 seconds) the target is silenced.

R - Volcanic (Dagger/Spear/Whip/Boomerang(of course the boomerang would return)) - Sala slings his (?) in a line setting the earth on fire. Anyone hit by his (?) is dealt 275/450/625 physical damage that ignores 15% of the targets armor. The path his (?) takes is set ablaze. causing enemy units to burn for 3 seconds for a total of 40/50/60 magic damage.

Rival would be Fizz

Please give me feed back on concept art, ability changes, and even lore ideas! Thanks for looking
