Warning:This is an experimental find and i am not held liable if you brick your device (go into twrp and start over)

Installing Magisk in a Dual Boot Environment:

Things you need

(i advise to save all to your external card if you have one so it wont be erased):

Need to Create:

primary rom

secondary rom

gapps (unless you prefer one in link)

gapps in secondary (dual)

included in following link:http://www.mediafire.com/folder/95yswgomsz3d3/Magiskdualboot

gapps aroma(both normal and dual)

no verity zip(both normal and dual)

su remove(both normal and dual)

magisk 14.3 dualboot

dualbootutilities(just in case something goes wrong)

Dual boot patcher app

Step One:

Assuming your on the latest twrp for this rom (check official twrp app)

you will want to go to wipe in twrp and wipe data,

reboot to recovery,wipe advanced options and wipe everything except internal storaage and external storage then reboot into recovery again

Step 2:install primary rom,no verity,gapps,remove su addon,and magisk 14.3 dualboot zip.

(when everything loads set it up as you would normally making sure everythings up to date from play store,magisk manager update,etc

Step 3:install every magisk module you wish to have and reboot (once rebooted go into modules and unclick everything and reboot)

Step 4:get a root file manager and go into /data/adb in the root folder (make a copy of magisk.img and put on your sdcard)

step 5:install dual boot patcher app,run it,grant permission and when it asks to set kernal do so (everytime you change a rom it may ask you to set kernal)

step 6:use the patch zip file to patch your primary rom as an upgrade,then flash the patched primary rom then reboot to system (this allows nonconflict with other roms to avoid error and enables app sharing on the app)

step 7:assuming you downloaded the secondary rom,go to patch zip file section in the patcher app and add flash file and select your second rom zip and put it under secondary slot

step 8: patch as well in secondary:no verity zip,su remove zip and gapps.install the patched dual rom and files in twrp then reboot to system (it should start setting up your second rom)

step 9:update everything in second rom from play store plus do the setup

step 10:reboot back into recovery and install the dualboot magisk 14.3 zip again.reboot system and update that magisk manager and zip

step 11:install dual boot patcher app on the second rom now and itll ask you to set second kernal when you go to roms,do so

step 12:reboot back to recovery and then go advanced>file manager and then go /data/adb and select magisk.img copy file to data/multiboot/dual/data/adb/ then reboot to system.

step 13:now when you reboot into second rom you will notice in modules in magisk manager all the modules you had in primary are there

(be careful when enabling some as some will not work but its a small list)

(Warning:if theres any updates to any app you need to follow steps 12 and 13.

installing modules directly from the manager in second rom can cause bricks or crashes)

Step 14:have Fun
