The idea is very, very good and it would be hype for Deca to consider adding it, but it needs a few touches to have a better execution with the current direction of the game if it’s ever added:
1 - The biggest issue by far is that while the Dragon God Draconis fight is an extremely good one, it’s also looking to be yet another discord-only fight (even more than Void Entity) with how insanely difficult you made to access it, the fact you have to do several LoDs each in a different order and also several Sky Sanctuaries for random Gem drops just to get one single attempt at the buffed LoD is frankly, nothing short of ridiculous without a discord, the Unified Gem should probably be made a permanent, not consumable item so it can be reasonably ran in realms and guilds, now, this could have the issue of often forcing buffed LoD on people who don’t want it, but you could just rework the Gem to spawn a fifth destructible statue at the start of LoD that triggers the buff if killed, making it optional even if used.
2 - This is much smaller but now that high endgame items are deliberately being made to be upgrades to similar items from previous tiers (Like Divinity compared to ASS), most of these items could be rebalanced, like the Katsuri and Monos which should be buffed to not be made redundant by Kusanagi. Or Solannos’ dagger being very similar to and completely outclassed by Avarice.
(Kusanagi has both better damage and better true range than Katsuri and Monos)
(This is extremely small but there’s already a waki called Amaterasu now lol)
3 - The Egg Prism is a very fun idea but it would probably fit the upcoming Summoner class better, Trickster’s already powerful and versatile enough as is.
4 - I think we already have enough group buffs as is in the current steamroll meta, Elixir of the Gods might have a very long cooldown but it’s still free and i can definitively see large groups becoming even more OP by using multiple at different intervals, a change that could combat this is that it could be made either a stronger but more common one use consumable (even stronger if made for yourself only), or an unlimited use consumable, for yourself only, but with a downside, making it an item for yourself only in general makes it more realistic to implement, as the whole idea of all classes being able to use a group buff for free is kinda awkward balance-wise to begin with so it probably shouldn’t exist.
5 - When the formula for exponential HP scaling is revealed you should probably add it here.
I have a question, has Deca ever mentioned or taken notice/interest of this idea? Seriously, it surpasses even Sanctuary imo, just needs a little bit of changes.
