Doctor Octopus gets a bad rap, so I thought I’d dig in to maths of his base attack.

His strike is already unusual in that it is range 3, and it has a wild ability that can increase the damage he does.

The wild ability gives a significant improvement over a straight 4 dice, and has a higher potential for spikes than 5 dice.
If you like to look at “expected” hits (a weighted average of the individual damage probabilities), 4 dice gives 2.25. Ock’s strike actually exactly matches 5 dice with 2.8125 hits.
So when you are evaluating Doc Ock, you could consider his strike to be range 3, 5 dice attack. That’s pretty decent on a 50mm based wall-crawler.
