Absolutely ridiculous Doom Bots Sion setup
Right guys, if you don't know about this you're going to have your mind blown. So it turns out Bots don't often target Sion's passive, and his passive still deals 10% max health damage per hit against these bots that have a bajillion health. You can slap bots around and 100-0 one or two of them basically every time you die. Especially level 100 Doom Bots. You'll likely get 20+ kills per game.
The Death Timer in this mode is so low you can run Teleport and high CDR so that whenever you do a death run you can either Teleport or use his Ultimate to get back into lane instantly. Sion can be used to hold a siege that would've been done with long ago, simply by using his mobility, CC and extreme punching power to keep even Doom Bots in line.
Build:
Be wary of Heimerdinger and Malzahar's Voidlings, they will eat you alive. Dodge Veigar's Dark Matter. Don't forget the one-two punch using Titanic Hydra's active.
Sion basically counts as 3 players at once in terms of effectiveness, and me and a friend playing Jinx managed to beat Doom Bots Level 100 with just us two pulling everyone else's weight. Riot disabled Brand for being stupendously powerful, do you think Sion will?
