This is a fairly standard build for Ornn, however the triple rejuv beads are used to help Ornn stay in lane allowing him to assert better lane control, win trades through sustain and get more xp and cs from stronger lane presence. You become quite tanky early on in lane by just earning gold and crafting armor, health etc which synergies with your bonus health regen. Buying the mana component will be needed at some point when you run low on mana, manaflow band is quite easy to stack and will also help. Try to complete your Sunfire Cape and Abyssal mask in time for level 13 as they will automatically upgrade and give you a big power spike.

Level 14 onwards you can help your allies by upgrading their items, 1 upgrade per person. Just click on an ally who you deem worthy and one of their items will be upgraded assuming it is compatible with a masterwork item. Split pushing and jungling for exp may be a viable strategy to allow you to upgrade your allies items faster.

This build does a lot of magic damage from W, brittle, grasp, Sunfire Cape and Thornmail which is why Wit's End is added because it steals magic resist from any opponent you hit. It also gives MR which does work nicely with this build and Orn's kit.

--csing--
Q can be used to easily cs from a distance it is basically an empowered autoattack, W can be used to clear multiple minions at a time and proccing brittle from it can ensure the last hit on a cannon. W is also a very effective tool for clearing jungle as well as leashing your jungler level 1. E probably should not be used for csing but can be used as a panic dash for any cs you are about to miss.

--trading--
You can easily poke with Q for a little safe damage to the opponent and it will also proc Grasp. Bami's Cinder helps here as it keeps you in combat so grasp will always be ready. If your opponent is silly enough to walk too close to you, you can simply press W then auto them which will proc brittle and also likely proc Grasp, this trade will do a lot of damage to them.
You can also all in combo from level 3 onwards by setting up you Q then using W on the enemy, then using E to charge into your q pillar and knock them up(stun is longer on brittle targets) then autoattack to proc brittle. Your Ultimate also makes the enemy brittle so it can be used before, during or after your all in in order to secure the kill.

Be careful when going all in or even just over extending into lane because it is hard to escape a gank or attack as Ornn, if you do have ulti you can use that to stun them and allow you to escape, you can also use you E to put some distance between you and the enemy. Generally when I get ganked I will just try and walk away and hope that I am tanky enough to survive.

- Open the shop anywhere and 'buy' an item to craft it on the spot
- Use Q to proc Grasp of the Undying and Manaflow Band
- E charge into your Q pillar instead of into the enemy
- R also makes enemies brittle
- 2 of your items upgrade into masterwork items automatically at level 13
- Upgrade your allies items by clicking on them(they must have a compatible item)
