(should hitting a dragon's tail really be the way to CC/kill them?
If the dragon is a hyper tank: yes.
Have the dragon lay down in front of his team (ala wind wall).
That.... would actually be an interesting champion.
Noodle, the serpent tank
P
That tickles:
Noodle has a long serpentine body which absorbs any bullets that touch it. He still suffers the full effects of anything absorbed.
Out of my way:
Noodle ignores unit collision.
Return to sender:
Noodle's secondary resource is a modified fury bar. When ever he is affected by an enemy attack or ability, he gains 3/4/5 fury (Triple gain from champions, Dragon, Baron, and Scuttle crab). If Noodle has more than 50 fury, it decays at 1 per second after 30 seconds of taking no damage.
Hunger
When ever a non-champion dies near Noodle (enemy, ally, or neutral) he devours their essence. Noodle gains 0.005% damage reduction for each stack of essence devoured.
Q
Coil:
Passive
Enemies that pass though Noodle are slowed.
Active:
Noodle coils up tightly (0.2 second channel) before dashing a moderate distance. If he collides with a champion (enemy or ally) he will encircle them.
(This ability does no damage.)
W
Presence:
Passive
Small spirit-like creatures surround Noodle. They start at 1 per [hit-box] and increase with each rank.
Active
Each spirit lashes out at a single enemy in a very small radius. Prioritizes Champions.
Enemies that are encircled are focused and take additional damage.
E
Favor:
Passive
Noodle doesn't hate you! . . Currently. . . Don't read too much into this; he will probably still eat you later.
Active
Noodle sheds his skin healing for a moderate amount. Allies can pick up the skin to also heal for a moderate amount.
Encircled allied champions immediately consume the skin and are cleansed of any CC.
If noodle somehow encircles multiple allies (Ghost), priority goes to hard CC'ed champions then lowest health champions.
R
Wrath:
Passive
Hunger
Active
Noodle Encircles target nearby enemy champion for 3 seconds. Noodle becomes rooted and enemies can not pass through him during Wrath (Azir ult style wall). Target champion takes 20/40/60% of all damage dealt to Noodle (pre-mitigation) and share any debuffs.
If the target champion dies during Wrath, Noodle gains 10 stacks of essence.
well that was a fun stream-of-consciousness concept. (>_>)
