Diablo 4 players have discovered a quick trick to farm 
Resplendent Sparks faster using alt characters. By using the seasonal reputation system and Infernal Warp, you can get free Sparks way faster and even save XP rewards for your main character.
In a related Reddit post, some players went over the Season 10 Warp Scrolls mechanic, and how they can help you get Resplendent Sparks from the reputation on alts faster!
The scrolls can be bought from the main campaign NPC next to the reputation board, and they grant around 6k reputation each. You need 250 Infernal Warp in order to buy one. Infernal Warp is earned by farming Chaos Rifts in Helltides or Nightmare Dungeon. You will obtain plenty to level your Chaos Perks on your main character, so you might as well make good use of the rest.
Step-by-Step Guide
- Farm Infernal Warp on your main: The fastest way is to farm Chaos Rifts in Helltides or Nightmare Dungeons.
- Buy Seasonal Rep Scrolls: Each scroll costs 250 Infernal Warp and gives around 6,000 reputation.
- Switch to an alt: Use the scrolls on your alt to instantly max out the Reputation Board. You need to stash the scrolls in order to be able to use them on your alt.
- Claim the Resplendent Spark: Your alt can now grab the free Spark.
- Save the XP rewards for your main: If you do not plan on playing any of your alts seriously, do not waste the XP rewards on these characters.
Turning Alts Into Free Sparks
Using alts, you can basically farm multiple sparks and keep all the valuable XP from the reputation board and loot for your main character. Using multiple scrolls per alt gives you the full reputation needed for a spark, so farming on a few alts can quickly be very rewarding, giving you many mythic uniques on your main.
This alt-farming method is a simple way to stack Resplendent Sparks and prepare for mythic uniques without grinding or losing too much time on bosses. For players looking to optimize their seasonal rewards, it is a great strategy worth a try.
