This is right now imo the best starter for Jorm. Maybe later on I'll do a build with tainted but rn axe is very strong, specially on jorm, so its basically a must to build it. (health potions do not appear here for some reason and thats why I picked chalice but you dont have gold enough in that build for chalice and multipot, you need to get 3 HEALTH POTS and 1 multipot, you can get chalice later)

This is the best build for Jorm rn I think. Since you dont have tainted in this build, you need the divine because everyone will outsustain you in lane no matter what you build, because Jorm doesn't get much value from lifesteal items (such as pythags). Also it is a good item to deal dmg on carries while applying antiheal on them. Since you have divine and bulwark/voidstone is no more, just pick your heartward amulet. You have a lot of physical defense in this build and amulet glyph will provide you with enough magic defense. After building the first four items, you should be 20 or near to it so just farm enough to pick your sundering axe. Finally, get stone of binding because archdruids doesnt work on Jorm and binding works very well on him specially with this build. If you like abyssal stone you can replace binding for it but I think binding is better. If there are something liek 4 physicals you could get binding and abyssal stone (instead of amulet). If youre laning against a magical in lane and they have like 3 magicals in their team, you might want this build but replacing breastplate for pridwen, do amulet second item and pridwen 3rd or 4th.

*Important note*: Since divine is much more expensive rn, it would be ideal to back when you have around 1350 gold or so (750 for divine t2 + 300 for tp upgrade + 300 of chalice) Trying to wait for full divine is very unlikely and you probably will not have gold enough for chalice and tp upgrade which is much more important to have in early. In your second back you get your full divine and maybe breastplate 2, depends of how the game goes. If you are laning against a physical once you have breastplate you wont have mana issues and you can make pressure on cd, and once you have glad shield they can't kill you and you can do very good dmg to them.
