How do I beat the end battle?

Pools of Darkness for the C64? I'm quite sure that Secret of the Silver Blades was the last AD&D-game for the C64.

But if you're really talking about Pools of Darkness, here are some hints:

• Take only human characters in your party. All other races have level limits for all classes but thief. In fact humans will often start with a higher level than the maximum level other races can achieve.
• Take six fighting classes (fighter, ranger, paladin) in your party and level them until they got 2 attacks/round. That would be level 13 for fighters and paladins and level 15 for rangers. Than change their classes: I recommend to change three of them to mage, one to cleric and one to thief. As soon as you get you characters up to level 14 (or 16, if they were rangers), they will get back their old abilities in addition to the abilities of the new class. So you have casters with lots of HP, that are able to use efficiently all kinds of weapons.
  • Instead of equipping you characters with heavy armour, give them rings of protection, cloaks, bracers, etc.. This way you will get the lowest AC. One of my characters got an AC of -21 wearing the following with DEX 18: Silver Shield +5, Bracers AC2, Ring of Prot. +3, Helm+4, Cloak of Prot. +4.
  • When you have created new characters you can choose to modify their attributes with the fitting option in the main menue.
  • You can keep your armour in the planes beyond limbo, if remove your characters from the party before going there and add one party-member as a dummy. After you arrived just replace the dummy with you original characters. I think you have to keep at least one character in you party before you add the dummy.
