Predecessor Builds > Sevarog > Severog tank offlane

The faster you stack souls, the sooner this build will come online because the max health increases the passives on your items. Look to last hit while damaging your opponent with Q. Look to invade jungle camps if safe. Be alert to minion waves when trading early, poke with your Q while last hitting. Once fire blossom is online you can take longer trades. You are most vulnerable early game with no Stacks so prioritize CS and stacks early. Green/Gold/Blue/Red buffs count as 5 stacks. So do player takedowns when hit with an ability.

Crest: Saphirs mantle helps make seve even more healthy and stacks into late game. Razor back may work well against a team with a lot of assasins building penetration.

Fire blossom is always first for magical damage and phys defence. Late game the passive damage increases as your health increases from further tank items and severog soul stacking.

Void helm you heal while immobilizing enemies while adding magical Defence and health (health procs fire blossom). This also helps survive ganks from mid or magical junglers.

Go wardens faith if enemy team builds crit or build tainted guard if they build life steal

Truesilver helps add extra survivability and damage once you are at max stacks because it is buffed by your max health when activating your ult.

Raimnant of renewal can come before truesilver if you do not have max sould stacks yet because the 600 hp will buff fire blossom.

Alternatives to last items.
Stonewall if late game carry is doing a lot of physical damage. Crystalline curiass if enemy team mages are stronger.
