If time is no issue, the objective is to make more damage/time than monster's life regeneration/time.
Assuming the character has a mid/low damage and lower chances to hit, against high hp monsters, the life regeneration must be stopped. A solution is to poison them. Those poison immune can be killed by 'open wounds' items, and physical and posion immunes only by 'prevent monster heal'.
Some other ways, are: 1. Increasing the chances to hit, by better AR or higher clvl; 2. Damage multipliers, against demons, undeads; 3. Crushing Blow or Deadly Strike; 4. Chances to cast Amplify Damage, from items or party; and/or the obvious, 5. Better weapon(s).
