Pit Fiend beaters, all damage comparisons are to +5 Metalline of Pure Good (+5 MoPG). I'm valuing things I'm after as follows: Major Mana potions 12k PP, Large Shrapnel 120k PP, Large Scale 300k PP, Red Scale 600k PP.
+2 Metalline Handaxe of Greater Lawful Outsider Bane (Suited to a capstone paladin only; 8 damage ahead of +5 MoPG) - 10 mana pots or 1 large Shrapnel
+5 Metalline Bastard Sword of Pure Good - 10 mana pots or 1 Shrapnel
+4 Metalline Dwarven Axe of Pure Good - 10 mana pots or 1 Shrapnel
+2 Holy Silver Heavy Pick of Righteousness (2.5 damage ahead of +5 MoPG) - 15 mana pots
+3 Holy Silver D-Axe of Tendon Slice 6% (1.5 damage ahead of +5 MoPG) - 15 mana pots
+4 Holy Silver D-Axe of Vertigo +4 (2.5 damage ahead of +5 MoPG) - 20 mana pots or 2 Shrapnel
+5 Holy Silver D-Axe of Shatter +4 (3.5 damage ahead of +5 MoPG) - 25 mana pots, or one large scale
+5 Holy Silver D-Axe of Enfeebling (3.5 damage ahead of +5 MoPG). Requires 24 UMD (or halfling race) - 25 mana pots, or one large scale
+3 Holy Burst Silver Bastard Sword of Backstabbing +1 (~4 damage ahead of +5 MoPG) - 15 mana pots
+2 Holy Burst Silver Greataxe of Parrying (~2.5 damage ahead of +5 MoPG) - 20 mana pots or 2 Shrapnel - NOTE - requires 22 UMD (or half-elf/elf/drow)
+4 Shocking Burst Silver Bastard Sword of Pure Good (~4 damage ahead of +5 MoPG) - 15 mana pots
+3 Metalline Battleaxe of Pure Good - 5 mana pots or 60k PP
+2 Holy Burst Shortbow of Greater Lawful Outsider Bane (2-3 damage behind a Lit 2) - 35 mana pots or 1 large scale plus 1 shrapnel
Lailat beaters:
+5 Seeker 4 Cold Iron Rapier of Pure Good: 10 mana pots or 1 Shrapnel
+5 Holy Cold Iron Rapier of Shattermantle: 1 large scale
+1 Holy Cold Iron Battleaxe of Maiming: 2 mana pots (not good enough for Epic)
+4 Holy Cold Iron Khopesh of Righteousness: 1 large scale
Velah beaters:
+1 Axiomatic Burst Icy Burst Falchion of Greater Dragon Bane (out-DPS's a Lightning 2 on the Dragon; utterly outclasses Mineral 2s) - 1 flawless red scale
High DPS non-DR breakers:
Trade pending +4 Vicious Dwarven Axe of Greater Evil Outsider Bane - 5 mana pots. Amazing in the hands of a capstone paladin against the Epic Cojoined Abashai Devastator, and acceptable in devil raids on normal (dealing 1-2 damage more than a +5 MoPG)
