Castle upgrades are the primary way to improve your hero in the PC game Rogue Legacy. With every generation of hero, you spend your money to upgrade your castle, unlocking new advantages and increasing the stats of your current and future heroes. Spending your money efficiently will make your game a lot easier, while spending your money poorly will slow down your progression. The following guide to castle upgrades in Rogue Legacy will help you make the right decisions.
Smithy (A+) – Until you purchase this, you can’t purchase any other upgrades. It unlocks the smithy which lets you buy armor and weapons.
Health Up (A+) – This is a critical upgrade both because it unlocks all future upgrades and because it increases the health of your hero. It is useful throughout the game and a great upgrade if you aren’t sure what else to buy.
Paladin Upgrade (A+) – The Paladin is not a particularly exceptional improvement over the Knight, but this upgrade unlocks your Equip Up, so you want to get it before buying anything from the smithy.
Equip Up (A+) – This upgrade allows you to use better equipment. It is particularly important to buy it early because the cost for it increases rapidly as you advance the level of your castle. This also unlocks the first choice in upgrades.
Enchantress (B) – This is an important upgrade because it lets you use runes, but the tree it unlocks is much weaker than the tree unlocked by Architect.
Architect (A-) – The architect lets you lock down the castle. This ability is one you will rarely use, but the upgrades unlocked by Architect are some of the best in the game. You should generally prioritize this, due to that fact.
Archmage Upgrade (B) – The Archmage is great in the mid to late game, but is a rather weak class early. The only good reason to buy this upgrade early is to eventually unlock Gold Gain Up.
Magic Damage Up (B) – Any pure stat increase is good, but magic is less helpful in the early game. Only buy this is if you don’t have something better available.
Attack Up (A+) – This upgrade is basically better than Gold Gain Up for getting gold early in the game because is will let you kill enemies in fewer hits, thus killing more of them.
Barbarian King Upgrade (A) – The actual upgrade is good, because it makes the already hearty Barbarian even harder to kill, but the real benefit is unlocking Shinobi.
Miner Unlock (C-) – Miner is a pretty lousy class, but if you buy this upgrade, you unlock Gold Gain Up, which is a good early upgrade.
Shinobi Unlock (A+) – Shinobi is the second best class in the game for defeating bosses and the best you can get before you have already beaten the game once. Get this early so you can take out the first boss and to start your path towards Armor Up.
Assassin Upgrade (D) – This upgrade with start you down the long path towards some truly amazing upgrades, but it is pretty useless and that path is a long way down the road.
Spelunker Upgrade (F) – Spelunker is practically worthless until very late in the game and this upgrade doesn’t open up any other options. Only buy this when you can afford nothing else.
Gold Gain Up (A) – Each step of this gives a 10% increase in gold gained, which doesn’t sound like much, but is a lot more meaningful when you remember that gold must be spent or lost. Buy the first level early and if you can afford it, the second level early as well. Once you have defeated the third boss, this isn’t much use anymore.
Crit Chance Up (B+) – This is a good upgrade, but Attack Up is better unless the cost ratio is at least double the cost of this upgrade. If you like using a Shinobi, don’t waste points on this.
Haggle (C+) – One level of this is essential, but after that, you want to hold off until later levels. This upgrade gets very useful once upgrades start costing so much gold that you have tons left over. Until then, just buy the first rank to unlock Lich and Hokage.
Potion Up (D-) – The only saving grace of this upgrade is that it unlocks Spellthief. Beyond that, a slight improvement to potions is a very weak benefit.
Crit Damage Up (C) – If you have equipment that makes critical hits more likely, this is a useful skill, but beyond that it only really helps Assassins, which is an otherwise weak class.
Lich Unlock (A-) – If you are patient, Lich is a very useful class for exploring new areas. If you aren’t patient, skip this upgrade entirely.
Hokage Unlock (A+) – The Hokage is actually a rather weak upgrade for the Shinobi, but that isn’t the reason to buy this. This unlocks Armor Up which is one of the best two stat increasing upgrades.
Spellthief Unlock (D) – Spellthief isn’t a completely terrible class, but it is on the lower end. You should hold off upgrading to this until you have an enormous amount of gold and can buy a few upgrades in a row.
Lich King Upgrade (C) – If you like the Lich and you don’t mind playing a risky game, you might as well buy this upgrade.
Armor Up (A+) – This upgrade is pretty much the best upgrade in the game. Whenever you can afford it, you should buy it up.
Down Strike Up (F) – Down Strike Up is a terrible upgrade. It improves your down strike, which is an attack you basically never use.
Spellsword Upgrade (B-) – The upgrade isn’t that great, but since you already have Spellthief, it is handy. More importantly, it unlocks Mana Cost Down.
Mana Cost Down (A-) – Once you finally start investing in this upgrade, spellcasters like the Archmage, Lich King, and Spellsword become much more viable. This is a great upgrade for increasing your versatility and it unlocks the best upgrade in the game.
Invul Time Up (C-) – You won’t really notice the effects of this upgrade until you have maxed it out, and even then it is small, but occasionally it will save you from serious damage. This also unlocks Dragons, which are a lot of fun.
Randomize Children (A+) – Buy this upgrade the moment you can afford it, no matter what else you can afford. It is the best upgrade in the game and gives you much more choice in each generation.
Beastiality (B+) – The Dragon is only slightly above average, but it is so much fun that this upgrade is worth buying eventually.
