Isisim Shrine is a Proving Grounds trial in Eldin with a twist in the name: the Constructs’ own Time Bombs are your best weapon, if you send them back.
1. Arm Up and Clear the First Floor
Arm up: Thick Stick, Wooden Stick and Old Wooden Shield lie to the left of the entrance.
Up the first ramp on the left: kill the Construct by melee, or hit the Time Bombs beside it and let them do the work.
Grab the Construct Bow by the ramp — the top floor needs it — and fuse the drops onto your sticks.
Back on the ground floor, Recall the gear and ride it up.

2. Recall Trick and Second Floor
The trick: bombs thrown at you can be Recalled in mid-air, sending them back to the thrower.
Up the next ramp, beat that Construct and take its Zonaite Longsword.

Inside YunoboCo HQ East Cave, directly north of Goron City in Eldin, at 1842, 2842, 0383. Red rocks block the cave, so you need Yunobo (partway through the Yunobo of Goron City quest) plus Flamebreaker armour or Fireproof Elixirs.
How do I deal with the Time Bombs in Isisim Shrine?
Use Recall on a bomb while it is still in the air — it retraces its flight back to the Construct that threw it and detonates there. It is the whole point of the "In Reverse" name.
What is the reward in Isisim Shrine?
A Magic Rod in the altar chamber chest, plus the Light of Blessing. Your own gear returns once every Construct is down.
