I've got a few suggestions to make, no new features.
1. Leadership - I do not see reason why leadership needs from G to P 155 books. While now it is surely easier to perfect it because of the hermits/exos drops ... still, why ? Poly , mining etc take a few just.
2. Back then there was a bug that doubled suras / warriors damage when using aura of sword / ench blade and going poly + leadership ap so in order to prevent that now you cannot use that skills when going in poly.
Considering the fact that other classes received a bonus of vs. monsters and that most monsters already have a higher amount of sword ( especially ) and 2hand resistance than bow / bell and that the skills are all being reworked maybe this bug can be solved and suras/warriors could gain some more damage in poly?
The approach on this server few years ago was to get players to do runs together by putting in place the IP block and also to make mages / sins useful so that plagued and ice run needed 1 of each mandatory to be able to finish the tasks.
My personal opinion regarding this choices is that they are wrong because you cannot force someone into doing something. If you want things to go in a certain direction then you must provide the environment so that the things go there. I think that it was proved that it was wrong due to the close death of the server. Luckly server 2 and corona pandemic revived it.
While suras or warriors will still not deal more than mages or sins in poly I think it would be fair to the current setup to gain a little more damage from aura / blade as it is in fact their skill and their right.
3. Soul stones are now very cheap. Since you develop a new system - S Skills - maybe you can find a use to the soul stones. Let's say a crafting option that involves soul stones like the ticket to the dungeon to require 100 soul stones, something like that as you feel appropiate.
4. Hell run is a level 100 dungeon while Ice run is 90 level but nemere and yamahon have the same level. The dungeons are similar in difficulty , I do not understand the difference in level.
Maybe make nemere level 110 then ? It simply makes no sense to have an entry lvl at a dungeon lvl 90 and the boss to be 30 lvls higher.
Also Nemere have way better drops than yamahon. Pearls drop chance is higher , you get ice grail + lucky mall punch box + alchemy chest over just a flame keystone in hell run which is a higher lvl dungeon.
5. stones +7 - WHile I know many hate even the +6 stones ... I'm going to try this ... for ex. def +7 = 150 ac + 5% avg res / mob. magic +7 = magic attk + 5% skill dmg.
6. belts - other than pvp belts which have their obvious meaning and vs mob belt + lvl 50 copper belt...all the others are completely useless. can they be somehow boosted? no suggestions here.
7. Monster info - you've added drop info on all monsters but can't it be possible to add there a little description like " versus devil / regenerates 10% hp every 7 seconds / skill resistance / ice resistance / spawn every 1 hour ".
Personally, since I find this an easy job I could help you out with this.
Looking forward to your opinions everybody!
