Just some suggestions for some new effects and perhaps some events or ways to bring them out
Monster series: we alredy have an undead. Perhaps these can be similarly obtained while questioning for eggs or randomly given while exploring or by a site wide event or by completing seasonal quests.
1. Infected: oozing bumps sloughing flesh gaping mouths vacant eyed. Good as a random thing that can take place any time of year as a virus or infection possibly from uldavi perhaps the reason the uldavi gates were closed. Perhaps avalable as a syringe of infected fluid from the uldavian shops or by way of random infection while exploring during certan outbreaks.
2. Ghost: ghost verson of creatu glowing see through looking whispy bits like the jaaku. Good Halloween effect. Per haps an item that revives the creatus soul but not its body.
3. Warebeast: beefed up with shaggy fur glowing eyes long claws fangs feral looking. Good Halloween effect perhaps given randomly while exploring many creatu can be bitten by something while on explore.
4 machine/cyborg: creatu caught in the middle of turning into mechanical versions of them selves perhaps as the result of an uldavian technology gone bad another good reason the gates may have been closed. Jar of nano machines from the uldavian shop.
5 Stone, medusa's curse or golem: Creatu are stone. Glowing eyes and glowing cracks on the surface may have moss on them perhaps chipped or broken bits. This would be good for Halloween but could be possibly adapted for a fall effect.
The keyhole is no longer used. We could place a statue on the other side of it to access once the keyhole is open useing the carved skulls like the last time. Then offer the statue things. If halloween event could use items given by the pit or whatever it's called and other items but not the items found during egg hunting. Those are alredy food for the pit. Use items that you get from the pit or other events. By useing items that are a bit harder to get it makes it a little harder to get the curse. If for fall could use food, fall themed or event items items. These offerings could either please or displease the cursed statue. If happy it gives tu or relcoins if angry it places the curse.
Seasonal effects: some effects are alredy seasonal like frost light but some events or seasons have no effects.
1 Easter: We have ageless extract but what about an effect that can make a creatu pastel versions of colors with some markings like dyed eggs and has fresh fowers and green leaves braided in its hair or something.
2.new years: what about a super cute chubby baby version effect.
3.Thanksgiving. what about creatu in more earthy tones of their colors with sticks fall leaves and dried flowers in there hair or something.
4. Spring: leafy flowersy versions of themselves. Avalable as an site wide rvent or quest event between seasonals
Random things:
Squishy: turn creatu into full versions of the plushies perhaps given out as a rare high tier item by the springs could alternate to a creepy doll effect like threadbare with button eyes and loose stitching in spooktober.
Fairy: fairy versions by way of site wide random special events leading to quests to get the effect would be a good spring filler between seasonal activites.
Devine or blessed: oposite of curse of the undead. Angelic light colored feathered versions with gold trim on nails horns ect. Possibly made avalable between seasonal events as a special resurrection quest and used as a resurrection item like curse of the undead around the resmas events or easter could also make the effect avalable through the credit shop around those times as a special resurrection item.
Light: creatu glows looks like it's made of light. Could be a good summer spring or easter effect by way of a limited time quest or as a reward or special item could even be given at random from the carnival like the mahina eggs.
