Rocket drill (Q) – Launches anchoring drill, slowing and damaging enemies in a small area. Then allows launch towards drill, stunning and damaging enemies within range.
Headsmash (R) – Deals mixed damage to a target. Also applies recoil damage to Loadstone.
Loadstone Plates (E) – Passive ability which heals a percentage of incoming damage. It uses charges which accumulate over time.
Shatterstorm (R) – Ultimate ability. Gains damage reduction for 5 seconds, resulting in Loadstone’s armor shattering, dealing damage and slowing nearby enemies. All attacks made against the affected enemies will ignore any armor – both physical and magic. The same is valid for Loadstone himself.
With Loadstone you will have to focus on increasing his survivability and add as much durability as possible. Being an initiator he will be an easy target. Get Helm of the Black Legion early so you can gank safely even close to towers. Portal Key will be a must to be able to initiate effectivly in teamfights and land your ultimate in the best way. Shrunken head will prevent you from being stunned or disabled once you use your portal key as well as it will keep you safe from any magic damage. For the physical damage get Sol’s Bulwark and upgrade it to Daemonic Breastplate. Behemot’s Heart is also a great choice for Loadstone, considering the fact he is a strength hero. Frostfield Plate could be a nice touch, too.
During the laning phase, make use of his Rocket Drill ability to get kills on fragile targets. Slow it first, then stun it once the slow is over. With the help of your partner you should be able to control the lane. Gank the other lanes as often as you can – the slow and stun from Rocket Drill is very efficient and will give your team nice early kills. Once you get your portal key, look for opportunities to start a team fight, where you could use your ultimate at its full potential.
