Enemies
Urgles
Urgles have a small chance at dropping vit
Urgle gains a 4th beam that pet stasises
Urgles become a lvl 14-20 quest monster (so that during those 2 minutes of realm closing you are in highlands instead of midlands to do quests, could possibly do this with minotaur and headless horseman as well)
The Undead
Hobbits and dwarves have a chance at turning undead upon death
Next Halloween the event zombies will naturally spawn around infected graves, a rare enemy that spawns in place of permanent graves in midlands up, killing one “cleanses” the grave
New Disgusted debuff, pretty much sick but for mana, caused by the undead enemies
Undead Elves within the midlands and Undead Flayers in the Godlands
Undead lair skeletons have a chance of becoming a small pile of bones upon death and then revive in 3 seconds
Varieties
A normal sprite, which is purple and more sprite god varieties
More drake varieties
Multiple different shot patterns for the Djinn to chose from
New Shatters Enemy, Twilight Mage and Twilight Adept (only appear after the Forgotten Sentinel)
Baby scorpions come in multiple different colors (purely cosmetic)
Passive Animals
Passive Animals (drops different meats healing 50 hp, 50 mp, or 25 of both)
Fish in the ocean with Salmon that try to go upstream and Tuna that stat in the ocean and Pirahnas which deal contact damage and attempt to group up)
A day and night cycle for the realms (with certain enemies that only appear at night, and certain ones that only appear at day)
Made these up Just for the fun of it
Sandman Kings are attracted to each other, making bigger conventions, same goes for Hobbits
Beholder has an extremely low chance (lower than Tcaves) at dropping a Mountain Temple entrance, while Ents have a extremely low chance at dropping a Woodland Labyrinth entrance
Cube Gods
Cube God and LotLL both get setpieces
Another thing about the Cube Gods, they now insult your inferior shape
Waldo now replaces cube gods in the same way that beach bum replaces ghost ship, first person within 5 tiles of him gets a quest chest and he kills himself (he spawns extremely rarely)
Event God Drops
Instead of getting a white bag, Jade Golem drops greater attack (G1) and Garnet Golem drops greater defense (G1)
Beehemoths have a chance at dropping mana while the Lost Sentry has a chance at life (both slim, but a bonus that one would be happy to see)
Items
Weapon Changes
Cdirk gains slightly lower damage but a 150% rate of fire
Ray katana armor pierces, giving it the most stable dps in the game
Obsidian dagger becomes a weaker poison fang dagger, Poison Fang Dagger becomes a stronger obsidian dagger
Items from the Nexus
Equipment costing fame again (keys still cost gold)
Arena tickets from the daily reward calendar
Selling white bag items for realm gold
Other
All dungeon entrances gain multiple frames
Arena chests are gotten from every 50 arena stages, there loot tables would include a:
Guaranteed Mystery Stat Pot
Chances at Godlands dungeon keys
Chances at extra stat pots (all but mana or life)
Extremely slim chance (0.1%) of Bronze Silver or Gold Mystery Pet Stones or Skins
Mini Gladiator skins
Extremely slim chance (0.05%) at the 16x16 gladiator skin
Greater spd, dex, wis, or vit
(Chest idea inspired by comment from @FIuff )
More Godlands varieties (purely cosmetic)
New Arcane buff, works like healing but with mp given by new consumables from shatters and udl (Forgotten Essence for 15 seconds, Ectoplasm for 10 seconds)
Stepping in lava causing the burning debuff as well, doing 10 armor piercing damage every second for 10 seconds
