You know combining different damage types in spells is actually pretty clever and makes a huge difference once you get the hang of it. I found out that mixing stuff like frost and shock not only saves you mana but also helps deal with those annoying enemies that resist one type of damage. Its pretty cool how a split 100-damage spell between two elements only costs like 74 mana, while going all-in on one element would cost you 111 - definitely worth keeping in mind when youre crafting spells.

What i usually do for regular enemies is mix it up with like 30% of each element plus a bit of pure health damage, works like a charm. For those pesky vampires and trolls though, you'll want to stack more fire damage since they really hate that stuff. Maybe interesting - if you start your combo with a weakness spell first, the damage really adds up especially with frost damage.

The whole spell creation system is pretty flexible once you get into it. You can mess around with range and area effects, and dont forget to check out the vendors in different towns for new spell effects to learn. Took me a while to figure out all the combinations, but its honestly one of the most satisfying parts of playing a mage once you understand how it all works together.
