Holy shit, that's a very interesting idea! And I agree, this would absolutely be legendary tier. Combined with Beacon, this would have huge endgame potential, even if we left out the multicrit level bonus.
How about making his speed bonus per wave rather than per level. That way unicorn tears don't break him. And he'd need to be built early, which counters abuse related to SnoreFox.
Maybe +77% (+3%/round) bonus attack speed?
Edit: I'd be interested to see how the dps of this level 99 tower with 300 rounds compares with Blofeld with 400M gold and a 20x bonus from stonecutter.
What do you think about, integrating this tower with the current season's lore? The name of this tower would be Thor, God of Thunder. His attack would be a brutal lightning strike.
Prophecy: Rag Nar Rog
Thor arrives in Midgard to prevent the end of the world. (next tower drop is Thor)
With Thor's arrival Naglfar spawns and slowly approaches your base. When Naglfar reaches the base, it's game over.
Naglfar could be insanely strong and take about 200 waves to reach the base.
Of course, we would need to add some cool Mjölnir interaction with Thor :-D
Summoning Thor that way does seem cool.
He should be able to have lightning on every attack with Mjölnir.
I don't see Thor working as a super slow tower.
Unless we did something weird: Cowardly Thor.
Thor is afraid to fight up close without Mjölnir. He's taken to using a massive crossbow*.
When Thor uses Mjölnir, gets an additional attack (range 2, cooldown 2, ~50 base damage) and triggers lightning on every hit.
* Chosen Executioner was pictured to use one as well. Winding the crossbow is why the attack is so slow. I don't think I ever mentioned that in the other posts.
Edit:
I think I understand what you mean now. I was thinking of Thor the warrior in battle. With the lightning attack, this would be more like Thor the blacksmith, god of thunder, as you said.
Right.. A god that doesn't care about the mortals hurries and just moves a bit slower by default. But when he moves, it hits hard :-D
That could work. But I still like my idea of a holy assassin using a giant crossbow to snipe creeps once per wave.
I think making the speed bonus based on rounds should balance the tower. It might need some tweaking, but I don't see it being a tower that's built at the end of the bonus round to deal with Vir. Although, if the player has a huge amount of bonus speed from potions, I don't think that's it of the question.
I'm not worried about the multicrit bonus running out of control with Beacon because after ~20 multicrit, it's effect is limited by crit chance. Although, making +1/20 levels might work better. Or maybe +1/30 waves.

Instead of the speed bonus:
Slow and sure:
Won't attack more than once per 10 seconds. Instead will meditate before attacking.
Each meditation increases damage by 10% (max 10 stacks, +1/level)
Instead of the multicrit bonus, the bonus could be:
Line up the shot:
For each second since the last attack, deal +1% (+0.005%/level) (max 100%) of creep's health as bonus damage.
Cease fire (active):
Stop attacking until reactivated.

With these changes, the tower doesn't get any free stats, but gets to kill a creep every ~100 seconds. Hydra arrow, heroic cape will increase the bonus damage. Cease fire would allow challenges to be killed in 1 shot.
Right now it's more of a support tower. With higher base damage, it could maybe be a late-game Vir tower. I'm not sure. The Slow And Sure sounds good, but it's actually a huge nerf. Instead of attack speed scaling normally, it only helps 10% as much after the first 400% attack speed.
Edit: actually, making the bonus damage from Slow And Sure into this would be better:
10% (+0.1%/level) (max 10 stacks, +1/wave)
Now waves gets up to ~500-800 with the bonus round. And with enough beacon of light levels, the attack penalty isn't too strong.
