Crown Siege: Skill Tree and Upgrade Priorities

Where I put skill points and side currencies on my 100% file — mostly early money branch, then crowns for big spells and units.

Hub route: 100% walkthrough.

Skill tree layout

Direction	Branch
Up	Archers
Left	Scouts
Down	Money

What worked for me: money branch down so other nodes are affordable; bank gold between fights when the tree asks for it.

---

Gold upgrades (in battle + tree)

Node / habit	Detail
Starting gold	First affordable dawn pick; buy again when listed.
Double gold chance	+10% double gold; purchased again in circus era.
More gold from enemies	+100%.
More gold line	Max out the line when possible.
More gold from rage	Purchased mid run.
Red crystals	Click on field for lump sums (e.g. 6,000 gold).
Even more luck	Higher chance of gold, coins, rubies, diamonds from enemies.

Rule: Gold spent during a fight does not apply outside that fight.

---

Scout / archer / melee nodes (examples)

When	Nodes mentioned
Early	Scout damage, attack speed; +100 scout health; +10% melee damage.
Open field era	Tower health (twice), tower shot damage.
Knight era	Melee damage, archer speed, archer damage; knight attack speed/health.
Mid game	Night damage, melee armor, ranged health; ranged crit, archer health/damage/speed.
Late	Knight armor, tower spike damage, crossbow upgrades.

Crowns — what they unlocked for me

Cost	Purchase
1 crown	Tower regen — 1 health per second.
1 crown	Archer Double Shot.
1 crown	Banner invisibility.
1 crown	Necromancy unlock.
3 crowns	Trojan Horse.
4 crowns	Shadow Knight.
4 crowns	Paladin.
4 crowns	Astral Beam.

Arrow Rain — plan to spend next crown on it; cast with press 1.

Bank crowns for the big ticket buys — Shadow Knight, Paladin, Astral Beam — instead of spending on every small node.

---

Pedals

Source / use	Notes
Drops	Swamp enemies.
Gate	Swamp area requires pedals to unlock.
Buys	Automatic gold pickup.

---

Corn

Source	Uses
Farm (south), windmill, ruins, haunted farm, cornfields	Tank unlock requires corn.
	Golden Knight upgrade requires corn from farm.
	Knight upgrades; tank health; arrow rain damage with corn.

---

Firelands and embers

Part	Detail
Enter Firelands	Collect embers; level mage.
Spend embers	More gold/coins/rubies/diamonds from enemies; more gold.
Fire spell	Unlock fire spell; spend embers on starting gold.
Pyromancer	Upgrade pyromancer with embers.

Mages are expensive; leveled ones earn embers / set enemies on fire in my run.

---

Sparks

Source	Use
Gnomes and robots	Collect sparks.
Tesla tower	100% more sparks from gnome/robot fights.
Cloverfield rat rider	Farm sparks.
Spend	Tower fire arrows, fire damage.

---

Rubies and diamonds

Upgrade	Notes
Auto ruby pickup	Worth it before heavy spawn spam.
Auto diamond pickup	Near ruby pickup on tree.
Even more luck	Broader drop rates.

---

Early vs mid priority (my order)

Early habit:

1. Starting gold + double gold chance early.
2. Scout skill points for survival.
3. Money branch to unlock faster.
4. Tower health before ego DPS when bear riders appear.

Units and spell keys: Units, army, spells, and tower.
