An online perk planner would be a great help for this game

There is one at SkyrimPerks. (click 'calculator' in the banner). Don't know if it's accurate as it only allows 50 perks. Been reading you can get up to 81.

Skyrim nexus has offline versions.


Edit: The Skyrim Nexus versions says that the max perks is 100. You reach it when all skills are at 100 (81 perks) and you get the rest from quests.

Does anyone know how many perks one can actually have?
