Add Instance Dungeons as repetable and engaging pvm content
Currently, pvm content is restricted to open areas and very little coordination is required for most these. Adding instance dungeons would alternative and more interesting Experience Routes.
Orc Memory Dungeon should be ready to go within Hercules without any conflictive content.
Adding instance dungeons would give people an alternate EXP route, specially at high levels when it becomes a highly repetitive and mindless process. Instance dungeons add an extra layer of complexity to leveling a character and farming some items, they can't be farmed that easily, adds an extra challenge of how few people or how fast can you do some of these instances, gives another option to players and are overall fun to do.
Currently, these instances should work for pre-Renewal content:
% ls npc/instances EndlessTower.txt NydhoggsNest.txt OrcsMemory.txt SealedShrine.txt
From these, the only one that is a definitive No is Nydhogg's Nest, monsters are way too powerful for Pre-Trans and so are the rewards.
Orc Memory should be ready to go, it is just a mix of various Orc monsters with a private Orc Hero battle for the party. However, this instance is restricted to level 30~80 only, this restriction could be lifted, or not. This particular instance is specially useful to get new players into high level party range, or self farming efficiency range (without the need to go to boring places like Mi Gaos, Geographers, etc).
Sealed Shrine is a particularly difficult instance considering there are only pre-trans characters, with enemies like Zombie Masters and Banshees, classic characters can have a hard time dealing with this, so I heavily believe this would be a good addition. Obviously, since there are Banshees, Flame Skulls, and Ancient Mimics, the drops tables would need to be adjusted, I don't believe the cards are an issue (they all suck), but the gear they drop is an issue (Lever action Rifle, Black Leather Boots, Orlean's Gown, Wool Scarf, Scalpel, Fricco's Shoes, everything else is fine). The other main concern is the quest reward, which is the chance to create Giant Magestic Goat, and this can be turned into a Costume instead. So, very minor adjustments are needed for this instance to be introduced. Edit: Forgot to mention, items Pauldron, Tae Goo Lyeon, and Bloodied Shackle Ball would need to be removed from Sealed Baphomet's drop table, or maybe not, since this mob would be the most difficult enemy to kill in the current content by a long shot, same for the Giant MG, maybe not a costume but the actual item that maybe can't be used on GvG maps or without any restriction.
And finally, the big one, Endless Tower, this instance is one is already difficult to beat with fully geared trans characters, so for pre-trans is almost impossible. Another consideration, is that a lot of monsters that are not even close to being released can be found within, which includes their drops as well. Taking these previous 2 points into consideration, introducing Endless Tower would require a heavy amount of modifications, and probably would need to be shortened to 75 or 80 floors (this includes removing EC and NS fights). I can help with going floor by floor and making a list of which mobs and items would need to be removed to remove load from the staff, however, on the script side of things, I am unable to help since I am not familiar with instance coding (I can only create simple RO scripts).
