The recommended version burn of SDKA (Sepulchure's DoomKnight Armor) to use is the SDKA quest version, which dramatically reduces the grind time compared to the free player version. With SDKA, it takes around 42 days grinding 6-8 hours daily to collect the required resources like 7,500 Void Aura, while the free player quest can take over two years just for the Void Aura alone. Using SDKA makes grinding much faster and more manageable, significantly saving time and effort in obtaining SDKA and the Necrotic Sword of Doom (NSoD).
Therefore, it is best to use SDKA alongside a membership to benefit from this version's shorter and more efficient grind. The SDKA quest itself takes only about 5-10 minutes per session, compared to several hours for the free player quest.
This advice is specifically for grinding materials and progression in AQW related to SDKA and DoD upgrades. Let me know if more detailed guidance on this topic is needed.
