Obviously, it’s only viable if you’re ready to use a new character on an old realm with the story progressed/finished and/or hop between realms. So, if you want the whole and genuine experience of the game, just start with a new character and realm.
I’ve already seen a few posts mentioning that multiple bonus EXP buffs from sleeping on a bed in the Inn stack indefinitely. I assume it is a bug and unintended but use it while and if you can. Upgrade Caroline’s Inn in every one of your worlds, hop between them and sleep. Obviously use experience potions.
Now to probably one of the most impactful tips, mechanics you can abuse to level up your second characters fast. Weapons and armor parts’ requirements don’t change when you upgrade them. This means that you can have a level 16 Hunter’s Axe with basically no attribute requirement. Just start a new realm, go to Sacrament and buy or find a level 1 Hunter’s Axe and upgrade it all the way up to level 16. Yes, attributes scale the damage you deal but base item stats also matter. The same goes for armor. Obviously, diamonds for bonus EXP and a few enchantment power gems (they also amplify other gems’ bonuses) should be used on armor. You cannot slot diamond into weapons or shields so you can, if you want, put some enchantments into it. Or just use gems. My farmer build just below.
Obviously I use Battlecry Ring with a staff and rune caster/mage playstyle, Golden Band for another 10% bonus EXP and Willow cap for movement and cast speed. Every armor piece has a diamond, an elemental gem plus jewel for enchantment power and the last slot is occupied by dianite on gloves specifically (because they gain the most focus cost reduction of all armor slots) while every other piece has a skull for health regen.
I need to add that only certain weapons and armor sets/pieces can be obtained at level 1 and with virtually no stat requirements. You can only loot them in the early game and later on you will have to craft them. Some others can be only found or crafted with a certain minimal level and later in the game. It’s only important if you want to use a specific weapon and/or want to use it later, from level 1 to level 30 and more, as you will most likely replace your armor set with a more polished one of plagued or magical quality.
If I forgot something feel free to add. And if I’m wrong feel free to correct me. Like the post and recommend the game to your friends and family.
