'Right, it was like that, and that. Yes, combining the previous Tiers, it is almost like a combination of them all...' After a few minutes, Eldrian felt like he had managed to recall the module and its first two derivations, though he wasn't planning on using the derivations.
Naturally, with his research, he had also glanced a bit at higher Tier spells. But with everything that was going on Eldrian hadn't focused much on this. It was why he felt he just needed some time to practice and he would make some massive strides.
'Okay, so, I've got the module. Now the mana.' Thanks to all the practice over the past few months, Eldrian had massively improved his mana control. He fed it slowly to the spell module, which at first rejected the offered mana.
Eldrian then quickly altered the combination of water and darkness, slowly finding that something else was missing too. So he added some wind mana and also a speck of ether in the end.
'Oh, that did it?'
A bit of the math behind the damage system, for those curious about how the value between brackets (#) works. It is the value that magic armor will be subtracted against if applicable.
For example, target with 36 MR (Eldrian's breastplate's MR rating):
(54.6-36)*Int/100(3.27)=60.73 damage dealt per icicle that hits, instead of 178.
Frost damage will instead not be counted against the armor's MR, but a person's personal MR (resistances will be ignored, for simplicity, it is just a percentage reduction).
Eldrian has 4 MR at Tier 4, thus:
(12.5-4)*Int/100(3.27)=27.75 frost damage for 3 seconds. Instead of 40.81
Interestingly, if Eldrian uses {Shield} after his mana network upgrade, it will give him around 90 AR and MR if he hasn't cast anything before. Thus it could completely protect him against the spell and in fact most damage.
Continuous damage however will rapidly drain his mana and as it is drained {Shield} actively weakens.
