Abilities Build
Summary (TLDR)
This Riktor guide will be mainly for a TANK build.
Start off with Lord's Ward as your first item after getting 3 CP and the first items being Health Potion, Mana Potion, and Harvesters Key. Don't put anything into Lord's Ward until Tempered Plate and Tuned Barrier are fully upgraded.
Which brings us to our next items, Tempered Plate and Tuned Barrier. Both are basic needs and serve the purpose of tanking both aspects of damage. Max these as soon as you get them.
Or, if you get stupid fed and have a ton of CP to spend once you back, you could snap on an Etherweave Mesh or Quantum Casing, depending on which one of your enemies is fed the most. Either way, these two items will begin to complete your tank-iness. Max these when you get them.
Last item is just to add a bit of damage to the mix, while also adding even MORE health and making you an epic sponge monster.
All in all, this build will give you the max 40 percent cooldown reduction, needed for you to be pulling enemies in left and right, while also giving you 3630 Health and and getting to the 300 range on BOTH resistances.
Abilities upgrade priority
Square > Circle > R1 >Triangle > R2
Jungling
I like to try and gank AS SOON as the first wave of minions get to the lane. Left or Right lane works fine, and starting out with Riplash will almost always get your team a successful first blood if coordinated right.
Laning
Laning phase is weird for me. I tend to wander from left side to right side, assisting whichever needs help more and keeping middle harrased as I make my way through the map. If one side is losing badly, start supporting it full time.
