In Torchlight Infinite, there are some mistakes that new players may make in the game, so today I would like to introduce some tips you should focus on.
This is a mistake that I made myself, which is save your crafting mats. When we're on level 30 or so you'll start seeing mats drop, these include things like flame sand. You should save your flame sand until level 60 where you unlock the player market, then you can use it to buy some cheap legendaries or other items, that will give your character a much bigger boost than just crafting or enchanting your stuff at a low level.
As a bonus tip, you can do something similar with Flame Elementium when you get to a higher level, now Torchlight Infinite Flame Elementium doesn't start dropping until you're progressing in the endgame. When it does though you can often use it to go to the market and buy some Legendaries that are boss drops, which might be a little bit more expensive but can be much more powerful and build enabling. I found that a lot of these only cost a single Flame Elementium, so if you're looking for something to spice up your Buildes or maybe try something new, this could be the way to go.
Then the second one, don't forget Pact points, Pact points are a great way to get early resistances, Mana regen or damage, and you do not need Pact spirits to use these you get them just by leveling up. If you have a Pact Spirit equipped in the slot, it may change the effect for Point grants, but the point will exist and you can allocate it regardless even if you have zero Pact Spirits, so always allocate your Pact points.
Tip number three, you can Mass ID items. This is another mistake that I made when I first started playing the game, I would ID items one by one, however that little magnifying glass down bottom left will identify all the items in your inventory, which saves a lot of time and lets you quickly go through what you want to keep, and what you want to turn in at the vendor.
The next one is also important, don't forget to Dark surge. Dark surge is the current seasonal mechanic, and it gives you access to embryon cores which you can use to corrode your items. At low levels, it gives you access to free corrosion, corrosion can make your items better or add powerful implicit mods. You should always do all of your Dark surge at low level, and if you have some cheap items that you happen to be leveling, toss them in, there's not too much harm. You'll definitely want to think about it before potentially bricking an endgame item at low levels worst case, if it breaks you can replace it without too much trouble.
The last tips, you can replace your talents completely for free until Level 80. So when you're approaching level 80 take some time and experiment test changes, and when you find something that you're happy with, go ahead and continue to level up, you'll get a lot of power from your hero traits.
Once you hit level 80 or higher, you can still replace this using Oblivion points, they drop fairly commonly to the point. So once you get to 80, do a bunch of testing and make sure you're happy with your character before leveling up.
