New CHAMPION spell types (idea) or maby a gamemode for mages
Yes its not extremly creative but.. it would be cool that there will be a champion what can combine spells in a spell with a diferent effect.
For our test example lets say that Ziggz is the champion with these spell types.
Q - Bouncing bomb W - C4 what he can detonate E - Mine Field R - Mega bomb
Q + W = Bouncing C4 Q + E = After first ground impact they bounce scattered so the radius is bigger Q + R = After the bomb lands and doesent hit a enemy, it will roll like the Indiana Jones stone thingy and explode after some distance W + E = A minefield of C4-s and if you stand on them they will catapult you a bit to the side W + R = Your ultimate will fly in the air and slam into the ground with more force than normal ult and will nock enemieies a bit, and after 0.5 it will explode and do less damage but be similar to gragas ult. E + R = Throws the ult normaly, but when it falls down it will split into many smaller bombs and will have a larger radius but less damage, the bombs what dont detonate will still be on the ground for 2seconds and then dissapiere (doesent slow)
This is just a exmaple, there is no balance in this but this just shows what could it look like. After the spell is thrown the longer CD spell goes on CD but the lower CD spell will have a handicap for the next cast or a certain period of time. You throw spells by pressing the first and then while holding pressing the second if posible same time, the disadvantage here is that you cant play on smart cast (normal smart cast) here but that is something RIOT can figure out :) This could be even created for 3 combo spells or even 4!! combo spells for like a "Ultimate Ultimate" :D
For fun here:
Xerath: Q + W = Charges hes W and incrasing its radius Q + E = Incrasing its range and speed Q + R = A bit smaller than the ult range but instead of normal ults he is throwing long ranged Q-s W + E = On E impact it will explode and slow all enemies around it (and doing aoe damage) W + R = Same ult range but 10% less damage, your ults will have a 10% larger radius and will slow enemies (great if you suck at ulting and you still did not buy Crystal Scepter) E + R = The ult will be similar to Jhin ult but in a arc so that unless a enemy is protecting your target so that he is really colose to him you will hit the enemy, and your ults are really fast.
And for end, this could actualy be a cool gamemode for mage champions (like bloodmoon for assassins) .... tadah, RIOT some players play other roles too not just assassins :( (we want atention too)
I see that riot tryes new things so here is a new thing what would not need to change the form to work like "Nidale, Jayce, Shivana" and I think it would be cool :)... I hope RIOT doesent have the anoyng policy that they are not alowed to copy paste fan ideas.
