Everyone likes Lilarcor. Everyone likes the Mordenkainen's Sword spell. And everyone likes NPCs. So why not make Lilarcor into a floating sword NPC?
This is a simple mod that allows you to turn Lilarcor into a party member by speaking with the sword. He'll float around, poke your enemies, and deliver his typical dialog lines. Lilarcor possesses some unusual abilities, but has a number of distinct limitations to offset his various strengths. He has more item restrictions than a Wizard Slayer and the worst stats of any character I've ever seen in the IE games (his stat total is 51; a peasant's total is 54), but he also has sky-high APR and a reasonable set of immunities and resistances, all befitting a floating sword.
Starts at level 7 with only 1 proficiency point, in two-handed swords
3 base attacks per round
Immunity to charm, domination, fear, confusion, Hold Person, web effects, poison, disease, petrification, blindness, deafness, and Intelligence drain
Unable to use armor, helmets, boots, gauntlets, bracers, scrolls, or potions
Can only use one weapon, the +3 two-handed sword (you can use the Better Enchanted Weapon mod
to help him hit stuff like the Ravager, but he'll never be able to hurt Clay Golems)
50% fire resistance
80% cold resistance
40% electricity resistance
20% slashing resistance
-20% crushing resistance
40% piercing resistance
60% missile resistance
0 base AC
+2 penalty to AC vs. crushing
-2 bonus to AC vs. piercing
-4 bonus to AC vs. missiles
The mod is very young and has undergone only the barest of testing and no play-balancing, but it should stand up fairly well, as the mod is fairly simple and his advantages and disadvantages are both pretty impactful.
