Iguana Tweaks Reborn Mod 1.12.2/1.10.2 is a complete rewrite of the old 1.6 mod, IguanaTweaks, it adds various survival tweaks that make the game harder!
This mod is split in different modules. Every module can be disabled and every single feature of a module can be disabled and has the extensive configuration.
If the player attacks an entity without a tool/weapon, the attacked mob will take almost no damage (1/10 of a heart) and no knockback. The no knockback applies even if the player attack speed cooldown is below 75% with a tool/weapon, but in this case, the damage is applied normally.
This feature might have some unwanted behavior with modded mobs
Poison has been changed to be deadly and drain hunger on damage.
But will damage entities 3 times slower
Minecraft normally adds 0.005 exhaustion for block broken. With this enabled instead, exhaustion will be added based on block hardness (hardness / 100). ELI5 when you break a block you lose more hunger the harder is a block to break.
A multiplier in the config is available to increase/decrease exhaustion.
FoV will no longer change when the player speed changes (Especially useful if Movement Restriction module is enabled)
