Not Updated For Current Season
Lets try and make this short and sweet. This guide is not for new Pantheon players. So I am not going to explain much. I listed the items you should buy in the order you buy them. In this order you can go back about every 850-1850g and time this with your ults cool down to come crashing back into battle. If you coordinate this with your team devastation will occur. Oh course some defensive items will change according to the opposite team so just pick smart. If I have made any errors just point them out I will fix them(there might be a few I made this using a mobile device)
If you have questions please ask!
