Shadow Bolt and Incinerate especially.
The Classic version of Shadow Bolt was a clearly-defined energy ball made up of a black skull with glowing eyes, and a glowing sphere of purple, green, and white energies with a long tail, and when it hit the enemy, it would explode into a blast of green fel energy that felt like it had some impact.
Nowadays…you look at Shadow Bolt in retail, and it’s just a nondescript blob of black and purple goop that flies slowly toward an enemy and then just kinda…fizzles out, without any significant impact animation. It feels like you’re flinging a scoop of ice cream at somebody and it just kinda…plops.
Same thing with Incinerate. The spell originally, and for many years, was this broad, bright, burning patch of flame that snaked rhythmically toward an enemy, and when it reached, it leapt onto their body and set them on fire for a good 1-2 seconds, which really looked like you were throwing magical fire onto somebody’s skin and trying to burn them alive with it.
It looked amazing. There was a time when Incinerate was my favorite spell visual in the entire game.
Now…Incinerate in retail is basically just a color swap of Shadow Bolt. An orange and black blob that “kind of” snakes along the ground, and when it hits the enemy, it “kind of” leaps onto them…but really it just pops like a water balloon and there’s like a half-second flame splash that immediately vanishes.
Rain of Fire used to be physically distinct meteorites with a flaming streak…now it’s just the flaming streak with no visible meteorite.
So why is it that every time a spell effect is “updated,” it loses most of what made it cool and just becomes another cloud of nondescript particle effects with no satisfying visual impact on the enemy?
I have my particles turned up to Ultra, so it’s not just a graphics setting issue. Most of the spells just look worse now.
One thing I’ll say is that the new Drain Life, where it starts out purple and becomes green as it gets closer to your body, is a distinct upgrade over the old version which used to be a solid green piece of silly string. So it’s not ALL bad, it just feels like most “main” spells have gotten more generic over the years.
A lot of classes have this issue, but it’s most noticeable with Warlock in my opinion.
