Description
This mod allows you to spend dragon souls to improve some of your character
abilities. It is designed toward the late game when all shouts are
already unlocked and dragon souls become useless but you may as well use
it in early game. Go inside High Hrothgar where you will find a dragon
stone. To interact with the stone you must be acclaimed as Dragonborn by
completing the Greybeard's trials (retrieving The Horn of Jurgen
Windcaller and learning last word of Unrelenting Force shout). You can
then meditate at the stone and perform the ceremony to relinquish any
number of unspent dragon souls and redeem specific bonus via easy to use
interaction menu. Available bonuses are: Shout Recovery (reduces time
between shouts), Shout Power (increases damage of Fire Breath and Frost
Breath shouts), Perk Points (adds free perk points), Unarmed Damage,
Carry Weight and Attributes (health/magicka/stamina). Each bonus has its
own cost, increment value and maximum value.

Costs, Values, Balance and Tweaking
Some people will finish the game with no more than 20 unspent dragon souls while others might have as much as 200.

Default cost and increment values are set according to my own taste:

• Shout Recovery (max 50%, 1 soul = 2%)
• Shout Power (max 400%, 1 soul = 8%)
• Perk Points (max 100, 5 souls = 1 perk)
• Unarmed Damage (max 100, 1 soul = 4 damage)
• Carry Weight (max 500, 1 soul = 20 weight)
• Attributes (max 500 per attribute, 1 soul = 10 health or magicka or stamina)
  

It is not possible to reach ultimate balance and cater every play style so
you can tweak all the costs and values to your liking by using SkyUI
3.0 MCM interface or via console by changing some of the global
variables, if you find default ones imbalanced. Note that you can change
this at any time during game play but you cannot undo what you've
already invested (unless you're uninstalling the mod and stopping the
quest but I do not recommend doing that for sole purpose of resetting
because all tracking variables will also reset).

Global variable names (default values):
DSRShoutRecoveryCost (1)
DSRShoutRecoveryIncrement (2)%
DSRShoutRecoveryMaximum (50)%
DSRShoutPowerCost (1)
DSRShoutPowerIncrement (8)%
DSRShoutPowerMaximum (400)%
DSRPerkPointsCost (5)
DSRPerkPointsIncrement (1)
DSRPerkPointsMaximum (100)
DSRUnarmedDamageCost (1)
DSRUnarmedDamageIncrement (4)
DSRUnarmedDamageMaximum (100)
DSRCarryWeightCost (1)
DSRCarryWeightIncrement (20)
DSRCarryWeightMaximum (500)
DSRAttributesCost (1)
DSRAttributesIncrement (10)
DSRAttributesMaximum (500)

You notice there are 3 types of variables for each bonus: Cost, Increment
and Maximum. "Cost" is minimum number of dragon souls needed to increase
the bonus by "Increment" value. "Increment" is minimum bonus amount you
can get by investing "Cost" number of dragon souls. "Maximum" is a
total limit for the given bonus amount.
So for example if you want to make each bonus free perk point cost 10 dragon souls instead of 5 you
type in console (set DSRPerkPointsCost to 10). Furthermore, if you want
to gain 2 perks for these 10 dragon souls type (set
DSRPerkPointsIncrement to 2). Finally, if you want to make it so you
can't get more than 10 perks out of dragon souls type (set
DSRPerkPointsMaximum to 10), alternatively you can set "Maximum" to 0 to
make it unlimited.

Compatibility
DSR should be compatible with all mods. No shouts are being modified and
shout power is scaled via custom perk. Other bonuses are applied by
modifying related actor values. Only possible conflict is that this mod
uses one of custom actor values on player to store data for shout power
scaling perk. There are 10 of these actor values (Variable01-Variable10)
and other mods might use one of these for their own purpose. DSR can
use any of the 10 and it is chosen and maintained automatically. If some
other mod tries to change currently used actor value DSR will detect it
and automatically switch to another one that appears to be free,
eliminating all future conflicts with that specific mod.
