You will need to level up your Highdensity WATER stone to Tier 3 PLUS 3000 level in order to obtain the charged destiny, or you can simply buy it from Callidora located at -shop
You should have received a Tier 1 Highdensity WATER stone once you turn T3, you must now start doing Underworld Quest 1F,2F or 3F depends on your gear daily by talking to NPC Dwarven Emissary located at South of Windawood Castle. Once you picked a quest, simply walk to the entrance on your left.
Once you are in, look for 6 Blue Summon Stone located at the floor you picked. Here is what the blue summon stone looks like and location.
Now click on the Highdensity water stone it will summon several waves of mobs, I would recommend bringing a few immune of potion with you since they are pretty strong. Once you killed all mobs at each Blue Summon Stone, go back to NPC Dwarven Emissary turn in quest to level up your Highdensity WATER stone.
If you have already finished your daily quest, and you want to level up more here is another way to level up your Highdensity WATER stone.
Codex of Time > Page 2 > Asura Prison Chamber and if you are T3-T4 I would recommend doing Hard mode instead of Extreme. Normal gives 4 levels, Hard gives 8, and extreme will give 12. Do not use Potion of Learning or Eye of enemy health because it takes a long time to kill each.
In order to have 3000 levels on your Tier 3 Highdensity WATER stone, you will need a total of 5000 charges, each quest gives you certain amount of charges depending of the difficulty.
Add 1000 charges T1 Highdensity WATER stone > 1000 charges T2 Highdensity WATER stone > 3000 charges T3 Highdensity WATER stone > Charged Destiny.
When you have 3000 charges on your Highdensity WATER stone , teleport to Silveria Town, Nidrah is located at the very South of the map. You still need to keep doing these daily quest and Underworld Instances for T5 Skills
You will also need a Soul Key to turn T5. As of current version, you will just need to ask GM Zajako for Soul Key
