Do you think that Expert Mode is too hard but still want a challenge? Are Normal Mode bosses too boring?
Then this mod is probably for you! Boss Expertise makes bosses behave like they're in Expert Mode, even though their stats don't change.
BossExpertise also adds some optional features (like bosses dropping Treasure Bags in Normal Mode), which are disabled by default.
Also allows you to toggle Expert Mode via chat command (/expert), Cheat Sheet or HERO's Mod.

Big thanks to Pop000100 for maintaining the mod.

Adds in endless items.

These items act similar to the Endless Musket Pouch / Quiver and some, such as the throwables, are the same but do not consume themselves.

Website URL changed from the TCF link to the Discord link, since I'm not active on the forums anymore.
Changelog is now on the Discord, due to limitations on text.

With this, you can press Caps Lock to swap the top row of your inventory with the second row, and you can double tap a number on your keyboard to swap one item in the corresponding item slot with the one below.
The key for swapping the whole row can now be set in Keybindings. If Caps Lock doesn't work, check that it is bound in keybindings first.
You can also toggle the option to swap an item with just a single button press by pressing O. With this enabled, you will need to click on the items in your hot bar or use your mouse wheel to select different items in your hotbar.

This mod is the experimentation and implementation of projectile concepts. Test these out either by waiting for the merchant and buying it if you feel like getting them in the legit way, or just craft them with a single block of dirt. Please post a comment on the thread page on these experimental items!
Changelog for v5:
- Now can be played on the latest version of tModLoader!

This mod aims to fix a few grievances with summons and flesh out Summoner to be a fully developed class. This vision is of a summoner who has their hands full buffing and controlling minions and has little time for other weapons.

Includes 6 items:

Summoners Association Card - Displays summoner-related information
Minion Control Rod - Teleport your minions, select an enemy or spawn a reticle as a target
Blood Talisman - Sacrifice your own abilities to buff your minions at the cursor
Minion Selection Book - Allows summoning any minion from the inventory
Minion History Book - Allows summoning a set of minions from the inventory with one click
Automatic Minion History Book - Upgraded Minion History Book that summons a minion set automatically after respawn

Contains two configs: 'Server Config' contains settings related to the reticle from Minion Control Rod, while 'Client Config' contains settings related to the UI

If you experience issues with Minion Control Rods' reticle feature, let us know on the homepage; You can continue using this mod by disabling the feature in the 'Server Config'

Changelog:
v0.4.7.1:
* Fix Minion Control Rod reticle feature bug on "tml 64 bit"

v0.4.7:
* Add 1 new mod.Call (See the github)
