Planetar and Solar

Planetars and Solars are angelic beings in SLASH'EM which are both essentially stronger versions of Archons. They possess the same speed, alignment, armor class, magic resistance and spellcasting abilities of the Archon. They merely have a higher base level and their attacks do more damage, with the Planetar doing twice as much damage, and the Solar doing half again as much still. Like Archons, they are peaceful for lawful characters, and can even appear as minions for them, either through prayer or sacrifice.

Strategy
As with the devas, Planetars and Solars constitute a major reason that lawful is an easier alignment in SLASH'EM. However, in the case of these monsters, one should keep in mind that it is extremely unlikely that one will see these monsters before getting the Amulet, even with SLASH'EM's extended Dungeons of Doom. Thus, there is no reason to fight Planetars or Solars, even if one encounters them. A player in speed boots will be slightly faster than them, and wands of teleportation can work wonders in making them go away. Thus, just as one should keep a wand of digging handy for a chance encounter with a giant shoggoth, one should keep a wand of teleportation handy for these monsters. They are not covetous, so should not teleport to meet you.

If one insists on fighting these, either hope that your character is truly maxed out in fighting capabilities (+7 artifact weapon, Expert weapon skill, AC around -45), or have a cockatrice corpse handy. They are guaranteed a shield of reflection and resist just about every type of damage anyway. Using the disarm technique or a bullwhip to disarm them is a good way to reduce the damage they do, as well as bag yourself their guaranteed artifact weapon. They are also not immune to drain life, so the un-reflectable wand of draining can also be useful against them. Even with this, though, they remain truly formidable opponents.
