ultimasdrakonis: Dungeons will be fought with the same combat system as tournament only gear stats and jewels will be counted a dungeon raid will require 4-6 players in a party u will be able to choose 4 spells to take and buffs and heals can be cast on other players in the party during battle when your turn comes each spell will have a separate cool down depending on the spell there will be and attack button then each class will have a special attack such as amazon arrow volley which will deal reduced damage but hit all targets or paladin special attack defend will do greatly reduced damage but will cause the target to attack only the paladin for 5 attacks and the paladin will receive reduced damage from the target
The battle will consist of multiple 5 waves each wave having 5-10 monsters and waves will get harder with each one and finnaly you will face a boss with a few smaller monsters on last wave each wave completed players will receive special chests that give recipes runes jewels etc
There will be 3 chests iron silver gold then the boss will give a boss chest the boss chest will give 5 random rare items including recipes runes jewels credits diamond days a player can do 3 dungeons per day and cost 100 million gold to enter these dungeons need to be very very hard killing the boss should be almost impossible

Of course many other things can be added such as premium features such as pay 100c to get double exp and rewards or pay 25c to boost stats by 25% or pay 25 c to boost health by 25% other options in battle will be potions there should be a limit of potions per wave and u can upgrade your "potion belt" by finding certain items in dungeon then spending creds to use the items to upgrade the belt these items could also be used to permanently boost stats a little at a time just for the dungeon say we call them battle points and you get them for completing rounds say 100 per round and it takes 1000-10000 to upgrade something

Other features can include multiple dungeon brackets say a lvl 30-59.60-79.80-99 etc killing monsters will also give good exp and loads of gold and of course maybe a wooden chest that gives random items pieces gems runes recipes under lvl 80 and jewels etc

Spells cool downs should be like so
Buffs 15 seconds
Heals 20 seconds
Debuff 15 seconds
Damage 10 seconds

New heal spells should be added for this
Aswell as new support spell such as taunt which would cause the enemy to only attack u for a certain amount of time

Some damage spells should hit multiple monsters

And some spells deal damage say every 3 seconds like poison

Each element of damage spells should have a bonus effect say a monster normal attacks every 10 seconds an ice spell would slow it were it takes an additional 2 seconds to attack (not stackable)

Building teams and spell sets should take skill and strategies
