Personally, I'd like to share a few ideas on how a reworked Ocram could fight.
So obviously, keep Ocram's design the same beacuse that is honestly perfect how it is.
Ocram always moved quite, weirdly. His sprite would turn upside down as he shared the Eye of Cthulu's movement pattern which looked a little silly if I'm honest. It's hard to take a boss seriously when he's upside down half the time. So instead, why don't we make Ocram walk? I mean, those things on the side do look like legs afterall. He could perhaps jump up and levetate at times as well.
In terms of attacks, his servants could become deadly homing explosive attacks which have less of a spawn rate but deal a serious punch. The servants of course can be destroyed.
The main gem on his forehead could sometimes erup in a green laser barage, sending somewhat strong lasers flying all over the place.
Ocram could also have a charging attack, which wouldn't last too long but could deal serious damage, this attack could be easily avoided by staying off ground, though he could also have a leaping variant which isn't as strong but is able to hit airborne players.
Now I mentioned a feature where he would jump and levetate, well I have an idea. When he levetates he could open his mouth and unveil a vortex which sucks in players, if players get too close they will take continuous damage.
Oh, and since Ocram is land based he can't keep up with players very well.. So he has an ability just like the WoF where if you try going too far away he will use those green tendtils on his back to reel you back in. (In expert mode these could also poison you).
So that's phase 1 Ocram.
Phase 2 Ocram gets more challenging.
Remember his barrage of demon scythes? Well, let's bring those back. But green and more deadly. I feel like this attack had to come back just due to how memorable it was.
His other attacks would be more sporadic, dished out slightly faster and powerful, making him harder and less predictable. His defence would drop by a fair amount however.
His drops? Well, let's make his drops the exclusive console items! Items like the Tizona could be buffed up to the same power as the Duke Fishron items, this would mean these items are no longer craftable. Ocram could drop Souls of Blight again, though these would be used as a means to make his boss spawner easier to craft. His spawner would have two recipies, one being 30 Souls of Blight and the other would consist of 20 of each gem, perhaps 5 Souls of Night and maybe a new item called a Mysterious Gem, which would only spawn into the world once Golem has been defeated. These Mysterious Gems would naturally generate underground, they would emit a distinct green glow. 5 of these would be needed alongside the other materials to craft the Infected Gemstone, which would look just like Ocram's main gem. This would be Ocram's new spawner.
Once Ocram is defeated, a mesaage would appear saying something like:
'Powerful lifeforms detected, watch out...'
This would trigger every console exclusive enemy to start spawning into the world, they would have decreased spawn rates so they would be somewhat rare, however they would be much stronger than usual. These enemies could have a 1/200 chance to drop a Soul of Blight.
Ocram's drops are as followed:
Soul of Blight 25 - 40 (100%)
Greater Healing Potion 5 - 15 (100%)
Sparkly Wings (10%)
Ocram Mask (14.29%)
Ocram Trophy (10%)
Mysterious Gem Fragments 1 - 5 (100%)
5 Mysterious Gem Fragments are needed to craft 1 Mysterious Gem.
Ocram is guaranteed to only drop one of these items at a time:
Tizona
Tonbogiri
Sharanga (with Spectral Arrows)
Vulcan Repeater (with Vulcan Bolts)
Ocram also has a very rare chance to drop the following, only one may drop at a time though:
Vial of Blood (5%)
Beeswax (5%)
Wolf Fang (5%)
Brain (5%)
Petri Dish (5%)
Cabbage (5%)
Mysterious Gems can be used with bones to craft a Suspicous Looking Skull, which is Ocram's orginal, overpriced spawner. This item will simply act as a placeable lightsource which glows a nice green colour.
In expert mode, Ocram will be stronger and quicker and have a brand new move which causes Ocram to shoot out poison spikes. Ocram will drop a loot bag containing the various Ocram drops and a brand new item being a new accessory called the 'Infected Jewel'. This acessory grants you the power of Ocram, as you will shoot out green lasers when enemies get close with the occasional green demon scythe which can pass though walls. The item works just like Plantera's Spore Sac. Though the projectiles can't home in, but will shoot in the direction of the enemy.
Also this version of Ocram can be battled at any time of the day.
Well, that's my idea. I hope you enjoy my thoughts for a reworked Ocram!
