Day 1
On Day 1, you should immediately kill small enemies around where you spawn to reach at least level 3.
After that, head to the nearest Blood Loss and Fire settlement since these damage types are gonna be the places you have the chance of acquiring
Mohgwyn's Sacred Spear.
Since it is a Fire and Blood Loss weapon, loot every chest, and kill every enemy in hopes of finding the ideal weapon and additional weapons with any of the listed passive effects attached to them.
As always, look for churches and plan your route around them; always pass as many churches as possible since it’s the only source of healing upgrades.
Day 2
On Day 2, head back to the Blood Loss and Fire Settlements to look for upgrades for your weapon and start looking for World Bosses such as Carian Knights and Dragons, such as Ancient Dragon, these will have a high chance of dropping powerful character passives, called Dormant Powers.
Like Day 1, continue looking for churches and plan your route around them.
Day 3
Day 3, immediately check the merchant’s inventory, see if he has anything worth buying over leveling up, such as weapon upgrades (Smithing Stones) or use leftover runes for Greases to increase your damage output for the final boss fight.
