I don't know if this is a sign that I have too much time on my hands or not, but I wanted to make a charecter with the most worthless builds, and I ended up making a Magician charecter. I maxed out the illsion, pickpocketing, and lock smithing perk tree. I retired the Charcter shortly after got him Cisros outfit. It was nice though, since I never did any of the Dark Brotherhood quests before, but it was hard, its hard to play when you have no offesive perks. But I can finally close the book on my Magician build hero. It kinda feels like I just trolled myself though...

meh

Generally, illusion isn't thought of as being useless...but to each man their own. If you had fun with it, then bravo!

Yeah, Illusion is one of the best schools in the game. Should have went with destruction, used the highest leveled spells possible, take zero magicka reducing stuff and always dual cast, but never take impact. That is far more useless than Illusion.

illusion is good if you have offesive perks to go with it, but I had none..... And no sneak perks

That doesn't even sound fun imo.

Illusion is awesome. You decide when you want to fight Cast spell and make the mob kill eachother or make them run away.

Take that speech skill and try to convince the giant not to launch you in the orbit.

I did get tons of gold from the perks in pickpocketing and the lockpicking tree...... And Alexander the great, you are right it wasn't very fun, but I wanted a challenge.... It started to be really fun tho once I was getting the illion tree maxed out..... I made everyone in Solitude fight each other...

Here's a troll build:
Max out enchanting and make two different things: Fortify Alteration and Fortify Illusion so it's zero cost. So many lulz to be had. Just cast a frenzy spell and use buckets with your telekinesis spell to screw around with the battle. Then keep casting frenzies and fears. You can take out a whole city with nothing but frenzy spells.

Or you can just a troll by actually fighting a troll as a vampire lord, luring it to a body of water, and float over it.
