Video Overview------------
-------------Basic overview of the mod------
This is a multi-block reactor similar to Extreme/Big Reactors. However it is 100% passive generation with no fuel, coolant, or maintenance to keep running.
The mod is useless on its own and need a tech mod to power stuff.
Iskallium or is very rare so unless you are digging massive amount of land or use cheats, active power sources will tend to be easier short term. Iskallium ore drops iskallium essence (fortune and silk touch affects this ore)
Once you have 9 essence you can make a iskallium block. 1 block gets you 160 fe/t.
For steel you can craft it by default via 8 iron ingots around a coal block, or swap to the ingots in a blast furance recipe in the config.
Controller's are made with 1 steel block (9 steel ingots) and 1 iskallium essence
Power Taps are made with 1 steel block and 1 redstone.
Iskallium glass is 8 glass around an iskallium essence (tinted is the same but with tinted glass instead)
From there simply build a 3x3x3 reactor. the frame and the top and bottom rows need to be steel blocks with 2 exceptions. The sides can be iskallium glass(or the tinted variant) or steel casing. Lastly place 1 controller and 1 power tap(total, power taps that provide different outputs count to the 1 total). the controller can be place anywhere on the side faces besides the left and right edges of a side face. The power tap can be place anywhere on any face. Lastly place you iskallium blocks in the middle of the reactor.
What has changed from 1.12.2 to this 1.21.1 port?
Create Compability was added ~ New power tap can be made if create is installed, it provides 64rpm, and 128 SU per block (RPM is static). to make the create power tap combine a steel block with a create shaft.
Side by Side Reactors ~ Previously the mod would not work if you had a reactor next to a reactor, that is no more. Once a reactor is built once, given you dont remove a corner edge (the pillar from a top corner to its adjacent bottom corner) it will remember what reactor it is, and wont let other reactors use its blocks.
Tinted Iskallium Glass ~ Made a tinted variant of the glass so you can have better lighting control
Controller and Power Tap placement freedom ~ you can place the powertap anywhere on the faces and the controller anywhere besides the corner edges and the top/bottom plates. This lets you better view your collected iskallium.
Simple GUIs ~ The power tap and controller has simple but informative GUIs now.
Deepslate ore ~ while the texture was a simple edit, there is now a deeplate variant, both spawn in world but the old stone variant is slightly more rare.
Config Option galore ~ i made most adjustable option a config options. Don't like something? Config it.
Shape Freedom* ~ Build the reactors in any cube shape you want whether that 3x100x3 or 10x10x10.
* = unsure how much of this was already in the base mod, i swore i remember it being stuck to perfect cubes, if i am wrong ill remove this part.
I really enjoyed the mod back in 1.12.2 and wanted to see it in a more modern setting.
So i took the time to port it, make some adjustments, and polish it a bit.
